Safety of 3-Aminopropan-1-olIn 2020 ,《Syntheses, structures and catalysis of tetranuclear zinc N-alkoxide ketoiminate complexes for ring-opening polymerization of rac-lactide》 was published in Inorganic Chemistry Communications. The article was written by Yang, Chao; Peng, Ying; Wang, Jiao; Chen, Pengjiao; Gong, Xiaotang. The article contains the following contents:

Two tetranuclear zinc complexes 2a and 2b bearing tridentate N-alkoxide ketoiminate ligands have been synthesized and fully characterized by single-crystal x-ray structure anal., NMR spectroscopy together with elemental analyses. Both of 2a and 2b can act as active catalysts in the ring-opening polymerization (ROP) of racemic-lactide (rac-LA) without addnl. co-initiators, either in solution or under industrially preferred melt conditions (130° no solvent). To be noted, 2a and 2b show remarkable activities for bulk rac-LA polymerization even with low catalyst loading of 0.1 mol%, yielding polymers with high mol. weights (Mn) of up to 91,200 g/mol (2b), and very high turnover frequencies (TOF) of 19,000 h-1 (2b) and 19,800 h-1 (2a).

Formula: C3H9NOIn 2021 ,《Substituent Effect in the Reactions between Criegee Intermediates and 3-Aminopropanol》 was published in Journal of Physical Chemistry A. The article was written by Kuo, Mei-Tsan; Yang, Jie-Ning; Lin, Jim Jr-Min; Takahashi, Kaito. The article contains the following contents:

Via intramol. H atom transfer, 3-aminopropanol is more reactive toward Criegee intermediates, in comparison with amines or alcs. Here we accessed the substituent effect of Criegee intermediates in their reactions with 3-aminopropanol. Through real-time monitoring the concentrations of two Criegee intermediates with their strong UV absorption at 340 nm, the exptl. rate coefficients at 298 K (100-300 Torr) were determined to be (1.52 ± 0.08) x 10-11 and (1.44 ± 0.22) x 10-13 cm3 s-1 for the reactions of 3-aminopropanol with (CH3)2COO (acetone oxide) and CH2CHC(CH3)OO (Me vinyl ketone oxide), resp. Compared to our previous exptl. value for the reaction with syn-CH3CHOO, (1.24 ± 0.13) x 10-11 cm3 s-1, we can see that the Me substitution at the anti position has little effect on the reactivity while the vinyl substitution causes a drastic decrease in the reactivity. Our theor. calculations based on CCSD(T)-F12 energies reproduce this 2-order-of-magnitude decrease in the rate coefficient caused by the vinyl substitution. Using the activation strain model, we found that the interaction of Criegee intermediates with 3-aminopropanol is weaker for the case of vinyl substitution. This effect can be further rationalized by the delocalization of the LUMO for the vinyl-substituted Criegee intermediates. These results would help us better estimate the impact of similar reactions like the reactions of Criegee intermediates with water vapor, some of which could be difficult to measure exptl. but can be important in the atm. We also found that the B2PLYP-D3BJ/aug-cc-pVTZ calculation can reproduce the CCSD(T)-F12 reaction barrier energies within ca. 1 kcal mol-1, indicating that the use of the B2PLYP-D3BJ method is promising for future predictions of the reactions of larger Criegee intermediates. In the experimental materials used by the author, we found 3-Aminopropan-1-ol(cas: 156-87-6Formula: C3H9NO)

《Inverse Thermogelation of Aqueous Triblock Copolymer Solutions into Macroporous Shear-Thinning 3D Printable Inks》 was written by Hahn, Lukas; Maier, Matthias; Stahlhut, Philipp; Beudert, Matthias; Flegler, Vanessa; Forster, Stefan; Altmann, Alexander; Toeppke, Fabian; Fischer, Karl; Seiffert, Sebastian; Boettcher, Bettina; Luehmann, Tessa; Luxenhofer, Robert. HPLC of Formula: 156-87-6 And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Amphiphilic block copolymers that undergo (reversible) phys. gelation in aqueous media are of great interest in different areas including drug delivery, tissue engineering, regenerative medicine, and biofabrication. We investigated a small library of ABA-type triblock copolymers comprising poly(2-methyl-2-oxazoline) as the hydrophilic shell A and different aromatic poly(2-oxazoline)s and poly(2-oxazine)s cores B in an aqueous solution at different concentrations and temperatures Interestingly, aqueous solutions of poly(2-methyl-2-oxazoline)-block-poly(2-phenyl-2-oxazine)-block-poly(2-methyl-2-oxazoline) (PMeOx-b-PPheOzi-b-PMeOx) undergo inverse thermogelation below a critical temperature by forming a reversible nanoscale wormlike network. The viscoelastic properties of the resulting gel can be conveniently tailored by the concentration and the polymer composition Storage moduli of up to 110 kPa could be obtained while the material retains shear-thinning and rapid self-healing properties. We demonstrate three-dimensional (3D) printing of excellently defined and shape-persistent 24-layered scaffolds at different aqueous concentrations to highlight its application potential, e.g., in the research area of biofabrication. A macroporous microstructure, which is stable throughout the printing process, could be confirmed via cryo-SEM anal. The absence of cytotoxicity even at very high concentrations opens a wide range of different applications for this first-in-class material in the field of biomaterials. The experimental process involved the reaction of 3-Aminopropan-1-ol(cas: 156-87-6HPLC of Formula: 156-87-6)

In 2019,Fluid Phase Equilibria included an article by Leontiadis, Konstantinos; Tzimpilis, Evangelos; Aslanidou, Dimitra; Tsivintzelis, Ioannis. Application of 156-87-6. The article was titled 《Solubility of CO2 in 3-amino-1-propanol and in N-methyldiethanolamine aqueous solutions: Experimental investigation and correlation using the CPA equation of state》. The information in the text is summarized as follows:

The solubility of CO2 in 1.3M and 2M aqueous N-methyldiethanolamine (MDEA) and 3-amino-1-propanol (MPA) solutions was exptl. measured at 298, 313, 323 and 333 K, using a pressure decay method. Since only limited exptl. data exist in literature for MPA aqueous systems, the results of this study were compared with literature data mainly for 2M MDEA solutions, showing satisfactory agreement. The obtained new exptl. data were used to parameterize the Cubic-plus-Association (CPA) equation of state using a pseudo chem. reaction approach, i.e. to account for chem. interactions as very strong specific intermol. interactions, which is a crude approximation, but is necessary for applying equation of state models. It was found that the model satisfactorily describes the exptl. data using six or four binary parameters for the CO2-MPA or CO2-MDEA interactions, resp., which, however, are less than the number of adjustable parameters in similar literature models. The experimental part of the paper was very detailed, including the reaction process of 3-Aminopropan-1-ol(cas: 156-87-6Application of 156-87-6)

In 2022,Rizzarelli, Paola; La Carta, Stefania; Mirabella, Emanuele Francesco; Rapisarda, Marco; Impallomeni, Giuseppe published an article in Polymers (Basel, Switzerland). The title of the article was 《Sequencing Biodegradable and Potentially Biobased Polyesteramide of Sebacic Acid and 3-Amino-1-propanol by MALDI TOF-TOF Tandem Mass Spectrometry》.Application of 156-87-6 The author mentioned the following in the article:

Biodegradable and potentially biobased polyesteramide oligomers (PEA-Pro), obtained from melt condensation of sebacic acid and 3-amino-1-propanol, were characterized by NMR, matrix assisted laser desorption/ionization-time of flight/time of flight-mass spectrometry/mass spectrometry (MALDI-TOF/TOF-MS/MS), thermogravimetric anal. (TGA), and pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS). NMR anal. showed the presence of hydroxyl and amino terminal groups as well as carboxylic groups of the sebacate moiety. Hydroxyl and carboxyl termination had the same abundance, while the amine termination was 2.7-times less frequent. Information regarding the fragmentation pathways and ester/amide bond sequences was obtained by MALDI-TOF/TOF-MS/MS anal. performed on sodiated adducts of cyclic species and linear oligomers. Different end groups did not influence the observed fragmentation. Three fragmentation pathways were recognized. The β-hydrogen-transfer rearrangement, which leads to the selective scission of the -O-CH2- bonds, was the main mechanism. Abundant product ions originating from -CH2-CH2- (β-γ) bond cleavage in the sebacate moiety and less abundant ions formed by -O-CO- cleavages were also detected. TGA showed a major weight loss (74%) at 381°C and a second degradation step (22% weight loss) at 447°C. Py-GC/MS performed in the temperature range of 350-400°C displayed partial similarity between the degradation products and the main fragments detected in the MALDI-TOF/TOF-MS/MS experiments Degradation products derived from amide bonds were related to the formation of CN groups, in agreement with the literature. In the experiment, the researchers used 3-Aminopropan-1-ol(cas: 156-87-6Application of 156-87-6)

《DNA-Targeted NO Release Photoregulated by Green Light》 was written by Parisi, Cristina; Fraix, Aurore; Guglielmo, Stefano; Spyrakis, Francesca; Rolando, Barbara; Lazzarato, Loretta; Fruttero, Roberta; Gasco, Alberto; Sortino, Salvatore. COA of Formula: C3H9NO And the article was included in Chemistry – A European Journal in 2020. The article conveys some information:

A novel mol. hybrid has been designed and synthesized in which acridine orange (AO) is covalently linked to an N-nitrosoaniline derivative through an alkyl spacer. Photoexcitation of the AO antenna with the highly biocompatible green light results in intense fluorescence emission and triggers NO detachment from the N-nitroso appendage via an intramol. electron transfer. The presence of the AO moiety encourages the binding with DNA through both external and partially intercalative fashions, depending on the DNA:mol. hybrid molar ratio. Importantly, this dual-mode binding interaction with the biopolymer does not preclude the NO photoreleasing performances of the mol. hybrid, permitting NO to be photogenerated nearby DNA with an efficiency similar to that of the free mol. These properties make the presented compound an intriguing candidate for fundamental and potential applicative research studies where NO delivery in the DNA proximity precisely regulated by harmless green light is required. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6COA of Formula: C3H9NO)

With tertiary amines, an alkyl group may be displaced by a halogen.COA of Formula: C3H9NO

《Kinetics and new Bronsted correlations study of CO2 absorption into primary and secondary alkanolamine with and without steric-hindrance》 was published in Separation and Purification Technology in 2020. These research results belong to Liu, Sen; Ling, Hao; Gao, Hongxia; Tontiwachwuthikul, Paitoon; Liang, Zhiwu; Zhang, Haiyan. Safety of 3-Aminopropan-1-ol The article mentions the following:

To figure out the steric hindrance and its magnitude effects on CO2 absorption performance and Bronsted correlations of primary and secondary alkanolamines, the pKa values and kinetics data (second order reaction rate, k2) were investigated for nine alkanolamines at 293-313 K using pH meter and stopped-flow technique. The tested amines include monoethanolamine (MEA), diethanolamine (DEA), 2-methyl-ethynolamine (MAE), 2-ethyl-ethynolamine (EAE), 1-amino-2-propanol (1-AP), 3-amino-1-propanol (3-AP), 2-amino-2-methyl-1-propanol (AMP), 2-amino-1-propanol (2-AP) and 3-Amino-1,2-propanediol (3-APD). In addition, the equilibrium solubility of MEA, MAE, EAE, 2-AP and AMP were tested for evaluation of steric hindrance effect on carbamate’s stability. The comprehensive anal. of kinetics, solubility and Bronsted correlations indicated that the steric hindrance caused by alkyl group(s) attached to α-C atom has much significant effect on k2 and solubility than that caused by alkyl group connected to amino group. Moreover, the k2 and pKa values for sterically unhindered and hindered amines were sep. fitted at 293-313 K, giving out an AARD of 5.2% and 16.5% between predicted and exptl. k2, resp. Finally, based on mol. structures and exptl. results, mechanism of steric hindrance effect on reaction kinetics was proposed.

《Boosting the Efficiency and Stability of Perovskite Light-Emitting Devices by a 3-Amino-1-propanol-Tailored PEDOT:PSS Hole Transport Layer》 was published in ACS Applied Materials & Interfaces in 2020. These research results belong to Fan, Ruiting; Song, Li; Hu, Yongsheng; Guo, Xiaoyang; Liu, Xingyuan; Wang, Lishuang; Geng, Chong; Xu, Shu; Zhang, Yonghui; Zhang, Zihui; Luan, Nannan; Bi, Wengang. Application In Synthesis of 3-Aminopropan-1-ol The article mentions the following:

Properties of the underlying hole transport layer (HTL) in perovskite light-emitting devices (PeLEDs) play a critical role in determining the optoelectronic performance through influencing both the charge transport and the quality of the active perovskite emission layer (EML). This work focuses on manipulating the carrier transport behavior and obtaining a high-quality EML film by tailoring the poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL with previously unused amino alc. 3-amino-1-propanol (3AP). The modified PEDOT:PSS rendered a deeper work function that is more suitable for the hole injection from the HTL to EML. More importantly, the 3AP-modified PEDOT:PSS film can induce a low-dimensional perovskite phase that can passivate the defects in the EML, resulting in a significantly improved light emission. Such ameliorations consequently result in a dramatical enhancement in performance of PeLED with a low turn-on voltage of 2.54 V, a maximum luminance of 23033 cd/m2, a highest current efficiency of 29.38 cd/A, a corresponding maximum external quantum efficiency of 9.4%, and a prolonged lifetime of 6.1 h at a proper Cs/Pb ratio.

HPLC of Formula: 156-87-6This research focused ontryptophan synthase inhibitor antibiotics photoresponsive; antibiotics; azo compounds; enzymes; inhibitors; photopharmacology. The article conveys some information:

Light regulation of drug mols. has gained growing interest in biochem. and pharmacol. research in recent years. In addition, a serious need for novel mol. targets of antibiotics has emerged presently. Herein, the development of a photocontrollable, azobenzene-based antibiotic precursor towards tryptophan synthase (TS), an essential metabolic multienzyme complex in bacteria, is presented. The compound exhibited moderately strong inhibition of TS in its E configuration and five times lower inhibition strength in its Z configuration. A combination of biochem., crystallog., and computational analyses was used to characterize the inhibition mode of this compound Remarkably, binding of the inhibitor to a hitherto-unconsidered cavity results in an unproductive conformation of TS leading to noncompetitive inhibition of tryptophan production In conclusion, we created a promising lead compound for combating bacterial diseases, which targets an essential metabolic enzyme, and whose inhibition strength can be controlled with light.
