3D pharmacophore model for insect repellent activity and discovery of new repellent candidates was written by Bhattacharjee, Apurba K.;Dheranetra, Watanaporn;Nichols, Daniel A.;Gupta, Raj K.. And the article was included in QSAR & Combinatorial Science in 2005.Application of 115-84-4 The following contents are mentioned in the article:

To better understand the mechanism of insect repellency and to identify new repellent candidates, we performed a three-dimensional quant. structure-activity (QSAR) study and developed a pharmacophore model for potent repellent activity from a set of eleven known diverse insect repellent compounds by using the CATALYST 3D-QSAR methodol. The protection time for repellent activity of the compounds was taken from an earlier published study. The pharmacophore was found to have three hydrophobic sites (two aliphatic and one aromatic) and a hydrogen-bond acceptor site in specific locations in the three dimensional geometry of the mols. that are critical for potent repellent activity. The pharmacophore showed an excellent correlation (correlation = 0.9) between the exptl. protection time afforded by the compounds in the training set and their predicted protection time. The validity of the pharmacophore model goes beyond the list in the training set and is found to map well on a variety of other insect repellents. By mapping this model on one of the more potent analog we have generated a three-dimensional shape based template which allowed a search of our inhouse compound database and discover four new potential insect repellent candidates. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Application of 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Application of 115-84-4

Shape memory polymer foams synthesized using glycerol and hexanetriol for enhanced degradation resistance was written by Hasan, Sayyeda Marziya;Fletcher, Grace K.;Monroe, Mary Beth Browning;Wierzbicki, Mark A.;Nash, Landon D.;Maitland, Duncan J.. And the article was included in Polymers (Basel, Switzerland) in 2020.SDS of cas: 115-84-4 The following contents are mentioned in the article:

Shape memory polymer foams have been used in a wide range of medical applications, including, but not limited to, vessel occlusion and aneurysm treatment. This unique polymer system has been proven to shape-fill a void, which makes it useful for occlusion applications. While the shape memory polymer foam has superior performance and healing outcomes compared to its leading competitors, some device applications may benefit from longer material degradation times, or degradation-resistant formulations with increased fibrous encapsulation. In this study, biostable shape memory polymer foams were synthesized, and their phys. and chem. properties were characterized as an initial evaluation of feasibility for vascular occlusion applications. After characterizing their shape memory behavior in an aqueous environment, degradation of this polymer system was studied in vitro using accelerated oxidative and hydrolytic solutions Results indicated that the foams did not lose mass under oxidative or hydrolytic conditions, and they maintained high shape recovery in aqueous in vitro models. These degradation-resistant systems have potential for use in vascular occlusion and other wound healing applications that benefit from permanent, space-filling shape memory behavior. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4SDS of cas: 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.SDS of cas: 115-84-4

Corrosion performance of polyurethane hybrid coatings with encapsulated inhibitor was written by Alrashed, Maher M.;Jana, Sadhan;Soucek, Mark D.. And the article was included in Progress in Organic Coatings in 2019.Electric Literature of C9H20O2 The following contents are mentioned in the article:

Direct incorporation of inhibitor mols. in hybrid coatings results in premature deterioration of coatings performance. The inhibitor mols. interfere with curing of the organic coating and cause delamination due to fast leaching. This challenge is overcome in this work by encapsulating an effective organic inhibitor, 2-mercaptobenzothiazole (MBT), in polylactic acid (PLA) nanoparticles produced via nanopptn. method for corrosion protection of 2024-T3 aluminum alloy. The nanoparticles are designed as function of polylactic acid concentration, solvent/antisolvent volume ratio, and the PLA/MBT mass ratio. Nanoparticle size distribution, inhibitor loading percentage, and encapsulation efficiency are studied. The PLA nanoparticles with encapsulated MBT are incorporated in a polyurethane/polysiloxane hybrid coating and its properties are evaluated using impact resistance, pull-off strength, cross-hatch adhesion, pencil and pendulum hardness, and solvent resistance. The corrosion performance of the hybrid coatings is investigated by electrochem. impedance spectroscope (EIS) and potentiostatic polarization. The polyurethane/polysiloxane hybrid coating shows a 200-fold increase in corrosion induction time due to incorporation of MBT-impregnated PLA nanoparticles. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Electric Literature of C9H20O2).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Electric Literature of C9H20O2

Biological effects of combustion-derived particles from different biomass sources on human bronchial epithelial cells was written by Marchetti, Sara;Mollerup, Steen;Gutzkow, Kristine Bjerve;Rizzi, Cristiana;Skuland, Tonje;Refsnes, Magne;Colombo, Anita;Oevrevik, Johan;Mantecca, Paride;Holme, Joern Andreas. And the article was included in Toxicology In Vitro in 2021.Product Details of 115-84-4 The following contents are mentioned in the article:

Combustion-derived particles (CDPs), in particular from traffic, are regarded as a central contributor for adverse health effects linked to air pollution. Recently, also biomass burning has been recognized as an important source for CDPs. Here, the effects of CDPs (PM10) originating from burning of pellet, charcoal and wood on key processes associated to lung carcinogenesis were explored. Human bronchial epithelial cells (HBEC3-KT) were exposed to 2.5μg/cm2 of CDPs for 24 h and biol. effects were examined in terms of cytotoxicity, inflammation, epithelial to mesenchymal transition (EMT)-related effects, DNA damage and genotoxicity. Reduced cell migration, inflammation and modulation of various PM-associated genes were observed mainly after exposure to wood and pellet. In contrast, only particles from pellet burning induced alteration in cell proliferation and DNA damage, which resulted in cell cycle alterations. Charcoal instead, appeared in general less effective in inducing pro-carcinogenic effects. These results illustrate differences in the toxicol. profile due to the CDPs source. The different chem. compounds adsorbed on CDPs seemed to be central for particle properties, leading to an activation of various cellular signaling pathways involved in early steps of cancer progression. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Product Details of 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Product Details of 115-84-4

Equilibrium of boron extraction with 2-butyl-2-ethyl-1,3-propanediol and 2-ethylhexanol in butyl acetate was written by Kwon, Taeok;Hirata, Makoto;Hano, Tadashi;Yamagishi, Toshio. And the article was included in Separation Science and Technology in 2005.Electric Literature of C9H20O2 The following contents are mentioned in the article:

Boron extraction with 2-butyl-2-ethyl-1,3-propanediol (BEPD) and 2-ethylhexanol (EHA) in Bu acetate (BA) was carried out at various boron and extractants concentrations The distribution ratio of boron was constant for all boron concentrations when EHA was used as the extractant, and it increased with EHA concentration When high concentrations of BEPD were used as the extractant, the distribution ratio of boron was almost the same for all boron concentrations The distribution ratio of boron increased with BEPD concentrations An increase in the initial concentration of boron in the aqueous phase severely decreased the boron distribution ratio at low initial concentrations of BEPD in the organic phase. This was caused by the dissolution of BEPD into aqueous solution The loss of BEPD into the aqueous phase became severe as the concentration of boron in the aqueous phase increased. The loss of EHA was insignificant for all boron concentrations The distribution ratio of boron was plotted with a function of the equilibrium concentrations of the extractants. The plots showed a linear relation indicating that boron extraction resulted from the same mechanism in all the extraction systems examined in the present study. Distribution equations for all the extraction systems were derived. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Electric Literature of C9H20O2).

And the article was included in Inorganica Chimica Acta in 2010.Formula: C9H20O2 The following contents are mentioned in the article:

The gem-dialkyl effect was studied in the reactions of cyclotriphosphazene, N₃P₃Cl₆ 1, with various 2,2′-derivatives of 1,3-propandiol, CXY(CH₂OH)₂, in either THF or DCM to form spiro (6-membered) and ansa (8-membered ring) derivatives The reactions were made with a number of sym.-substituted (X = Y, Me, Et, Bu and a malonate ester) and unsym.-substituted (X ≠ Y, Me/H, Ph/H, Me/Pr, Et/Bu and Br/NO₂) 1,3-propandiols. The products were analyzed by ¹H and ³¹P NMR spectroscopy and some of the spiro and ansa derivatives were also characterized by x-ray crystallog. Reactions of 1 with unsym.-substituted 1,3-propandiols gave two structural isomers of ansa-substituted compounds, both isomers (endo and exo) were structurally-characterized by x-ray crystallog. for the Et/Bu derivative The regioselectivity of the reaction is changed when the base is changed. The relative proportions of spiro and ansa compounds formed under different reaction conditions were quantified by ³¹P NMR measurements of the reaction mixtures The results were rationalized mainly in terms of the electronic effect of the substituents, whereas the steric effect has a secondary role in the formation of both spiro and ansa compounds This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Formula: C9H20O2).

Novel random PBS-based copolymers containing aliphatic side chains for sustainable flexible food packaging was written by Guidotti, Giulia;Soccio, Michelina;Siracusa, Valentina;Gazzano, Massimo;Salatelli, Elisabetta;Munari, Andrea;Lotti, Nadia. And the article was included in Polymers (Basel, Switzerland) in 2017.Related Products of 115-84-4 The following contents are mentioned in the article:

In the last decade, there has been an increased interest from the food packaging industry toward the development and application of biodegradable and biobased plastics, to contribute to the sustainable economy and to reduce the huge environmental problem afflicting the planet. In this framework, the present paper describes the synthesis of novel PBS (poly(butylene succinate))-based random copolymers with different composition containing glycol sub-units characterized by alkyl pendant groups of different length. The prepared samples were subjected to mol., thermal, diffractometric and mech. characterization. The barrier performances to O₂, CO₂ and N₂ gases were also evaluated, envisioning for these new materials an application in food packaging. The presence of the side alkyl groups did not alter the thermal stability, whereas it significantly reduced the sample crystallinity degree, making these materials more flexible. The barrier properties were found to be worse than PBS; however, some of them were comparable to, or even better than, those of Low D. Polyethylene (LDPE), widely employed for flexible food packaging. The entity of variations in the final properties due to copolymerization were more modest in the case of the co-unit with short side Me groups, which, when included in the PBS crystal lattice, causes a more modest decrement of crystallinity degree. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Related Products of 115-84-4).

Kinetic Model of Linear Complex Esterification between 2-Butyl-2-ethyl-1,3-propanediol, Adipic Acid, and Octanoic Acid was written by Lehmus, Matti O.;Toppinen, Sami;Selaentaus, Maaria K.;Kopola, Nina M.;Krause, A. Outi I.. And the article was included in Industrial & Engineering Chemistry Research in 1999.Quality Control of 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

In the present study, a kinetic model of the autocatalyzed linear complex esterification of 2-butyl-2-ethyl-1,3-propanediol (BEPD), octanoic acid, and adipic acid was developed. The presented model describes complex esterification kinetics at low to intermediate conversions. For the first time, the concentrations of all components involved in the complex esterification reaction system were modeled individually, and the model was able to estimate accurately all 10 analyzed component concentrations in the entire temperature range studied. The model utilizes a simple second order rate law derived from the esterification mechanism to describe esterification kinetics. In order to avoid overparameterization of the model, simplifying assumptions regarding substitution effects were made which allowed the description of the entire set of 125 plausible esterification reactions with six kinetic parameters. The model was applied to both the simple polyol esterification of BEPD and octanoic acid and the complex esterification involving addnl. adipic acid, and all esterifications were carried out in the temperature range of 170-190 °C. As kinetic parameters of the simple polyol esterification could also be used in the modeling of the complex esterification, only four kinetic parameters were needed to be fitted simultaneously to describe complex esterification kinetics. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Quality Control of 2-Butyl-2-ethylpropane-1,3-diol).

Effects of Various 1,3-Propanediols on the Properties of Poly(propylene furandicarboxylate) was written by Wang, Jinggang;Sun, Liyuan;Shen, Zhisen;Zhu, Jin;Song, Xingliang;Liu, Xiaoqing. And the article was included in ACS Sustainable Chemistry & Engineering in 2019.Recommanded Product: 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

Diols or acids with different skeletal structures could be used to polymerize 2,5-furandicarboxylic acid (FDCA) to adjust the properties of FDCA-based polyesters. A series of FDCA polyesters with similar skeletal structure as poly(propylene furandicarboxylate) (PPF) were prepared from FDCA and 1,3-propanediols containing different substituent groups. The effect of substituent groups on the thermal properties and gas barrier behaviors were studied by differential scanning calorimetry (DSC), thermogravimetric anal. (TGA), dynamic mech. anal. (DMA), rheol. anal. (RA), and positron annihilation lifetime spectroscopy (PALS). The substituent -CH₃ significantly influenced the thermal properties of the polyesters, where the glass transition temperature (T_g) and crystallizability increased from PPF to poly(neopentyl glycol furandicarboxylate) (PNF) and then decreased from PNF to poly(2-ethyl-2-butyl-1,3-propylene furandicarboxylate) (PEBF). PNF displayed the highest T_g of 70 °C and T_m of 201 °C with a ΔH_m of 32.1 J/g. PPF possessed a T_m of 173 °C with ΔH_m of 0.9 J/g, while poly(2-methyl-1,3-propylene furandicarboxylate) (PMF) was an amorphous polyester. The gas barrier properties followed the trend of PPF > PMF > PNF due to the increased β relaxation and fractional free volume (FFV) after the introduction of lateral -CH₃ groups.

Linear glycidyl carbamate (GC) resins for highly flexible coatings was written by Harkal, Umesh D.;Muehlberg, Andrew J.;Webster, Dean C.. And the article was included in Journal of Coatings Technology and Research in 2013.Reference of 115-84-4 The following contents are mentioned in the article:

An approach to the design of highly flexible coatings based on glycidyl carbamate (GC) chem. is presented. In past work, GC resins had been synthesized by reacting polyisocyanates such as hexamethylene diisocyanate biuret or hexamethylene diisocyanate isocyanurate resins with glycidol. When crosslinked with amines, due to their high functionality, these resins form hard and tough coatings, but the coatings have limited flexibility. To obtain coatings with good flexibility, several GC resins were synthesized using linear and cycloaliphatic diisocyanates and a combination of diols and triol with glycidol. The combination of linear diisocyanates and diols introduces a more linear structure in the GC resin compositions Crosslinked coatings were obtained using two amine crosslinkers, para-aminocyclohexyl methane (PACM) and a com. polyamide, Ancamide-2353 (A-2353). The flexibility of the coatings was characterized using reverse impact test, GE impact test, and elongation at break in tensile test. The coatings were further characterized to determine their chem. resistance, hardness, thermal stability, and corrosion resistance. The diisocyanate composition and composition of diols and triol influenced the performance of the coatings. In order to understand the influence of the composition of the GC resins on their performance, coatings were characterized using differential scanning calorimetry and dynamic mech. anal. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Reference of 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Reference of 115-84-4
