On May 31, 2005, Kuramshin, A. I.; Asafyeva, E. V.; Cherkasov, R. A. published an article.Formula: C9H21N3O3 The title of the article was Preparation of Complexes η4-4-(1,3-Diphenyl-2-propen-1-one)-η3-3-(1,3,5-triorganyl-1,3,5-triazacyclohexane)carbonyltungsten(0) and Their Reactions with Diethyl Phosphite. And the article contained the following:

New W complexes were prepared of a composition η3-[(1,3,5-triorganyl)-1,3,5-triazacyclohexane]tricarbonyltungsten(0) where a tridentate coordination of the triazinane fragment to the metal center was found. The reaction of tricarbonyl triazinane W complexes with 1,3-diphenyl-2-propen-1-one (chalcone) under thermochem. activation resulted in replacement of two CO mols. in the coordination sphere of W by a chalcone mol. linked to the transition metal atom through a system of π-bonds C:C and C:O. The phosphorylation of η4-(1,3-diphenyl-2-propen-1-one)-η3-[(1,3,5-triphenyl)-1,3,5-triazacyclohexane]monocarbonyltungsten(0) with di-Et phosphite occurred at the carbonyl group of the coordinated heterodiene; the phosphonate thus formed underwent intra-complex phosphonate-phosphate rearrangement affording an organometallic phosphate. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Formula: C9H21N3O3

On November 30, 2022, Dieguez-Santana, Karel; Nachimba-Mayanchi, Manuel Mesias; Puris, Amilkar; Gutierrez, Roldan Torres; Gonzalez-Diaz, Humberto published an article.Computed Properties of 4719-04-4 The title of the article was Prediction of acute toxicity of pesticides for Americamysis bahia using linear and nonlinear QSTR modelling approaches. And the article contained the following:

Globally, pesticides are toxic substances with wide applications. However, the widespread use of pesticides has received increasing attention from regulatory agencies due to their various acute and chronic effects on multiple organisms. In this study, Quant. Structure-Toxicity Relationship (QSTR) models were established using Multiple Linear Regression (MLR) and five Machine Learning (ML) algorithms to predict pesticide toxicity in Americamysis bahia. The most influential descriptors included in the MLR model are RBF, JGI2, nCbH, nRCOOR, nRSR, nPO4 and ‘Cl-090′, with pos. contributions to the dependent variable (neg. decimal logarithm of median lethal concentration at 96-h). The Random Forest (RF) regression model was superior amongst the five ML models. We observed higher values of R2 (0.812) and lower values of RMSE (0.595) and MAE (0.462) in the cross-validation training set and external validation set. Similarly, this study had a high level of fitness and was internally robust and externally predictive compared to models presented in similar studies. The results suggest that the developed QSTR models are suitable for reliably predicting the aquatic toxicity of structurally diverse pesticides and can be used for screening, prioritising new pesticides, filling data gaps and overcoming the limitations of in vivo and in vitro tests. The experimental process involved the reaction of 2,2’,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Computed Properties of 4719-04-4

On August 3, 2022, Tziotzi, Thomais G.; Mavromagoulos, Athanasios; Murrie, Mark; Dalgarno, Scott J.; Evangelisti, Marco; Brechin, Euan K.; Milios, Constantinos J. published an article.Electric Literature of 4719-04-4 The title of the article was Constructing “Closed” and “Open” {Mn8} Clusters. And the article contained the following:

Use of the 1,3,5-tri(2-hydroxyethyl)-1,3,5-triazacyclohexane ligand, LH3, in manganese chem. affords access to two structurally related {Mn8} clusters: a “closed” {MnIII6MnII2} puckered square wheel of formula [Mn8L2(LH)O3(OH)2(MeO)2Br(ImH)(H2O)3](Br)3 (1; imH = imidazole) and an “open” {MnIII8} rod of formula [MnIII8L2O4(aibH)2(aib)2(MeO)6(MeOH)2](NO3)2 (2, aibH = 2-amino-isobutyric acid). In each case the triaza ligands, L/LH, direct the formation of {Mn3} triangles with their N atoms preferentially bonding to the Jahn-Teller axes of the MnIII ions. Subsequent self-assembly is dependent on the anion of the Mn salt and the identity of the organic coligand employed-the terminally bonded imidazole and the chelating/bridging amino acid. The {Mn3} triangles fold up on themselves in 1, forming a wheel. However, the syn, syn-bridging carboxylates in 2 prevent this from happening, instead directing the formation of a linear rod. Magnetic susceptibility and magnetization measurements reveal competing ferro- and antiferromagnetic interactions in both complexes, the exchange being somewhat weaker in 1 due to the presence of MnII ions. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Electric Literature of 4719-04-4

On September 30, 2013, Friis, Ulrik F.; Menne, Torkil; Flyvholm, Mari-Ann; Bonde, Jens Peter E.; Johansen, Jeanne D. published an article.Related Products of 4719-04-4 The title of the article was Occupational allergic contact dermatitis diagnosed by a systematic stepwise exposure assessment of allergens in the work environment. And the article contained the following:

Background. Information on the presence of contact allergens and irritants is crucial for the diagnosis of occupational contact dermatitis. Ingredient lists and Material Safety Datasheets (MSDSs) may be incomplete. Objectives. To evaluate the workability of a systematic exposure assessment in consecutive patients with suspected occupational contact dermatitis, and to study how it could potentially aid correct diagnostic classification. Methods. A tool for systematic stepwise assessment of exposures in the work environment was developed, consisting of six steps spanning medical history and workplace visits. The program included 228 consecutive patients diagnosed with occupational contact dermatitis: all patients underwent a clin. examination, the stepwise exposure assessment, and extensive patch and prick testing. Results. Of the participants. 48.2% were classified as having occupational allergic contact dermatitis. The diagnosis was made at the stepwise exposure assessment for 50.0% of patients at Step 1 (medical history) and for 34.5% at Step 2 (ingredient labeling/MSDS). We found 132 different occupational allergens of relevance to the patients’ eczema of these, 78.0% were allergens not included in the European baseline series. Conclusions. Systematic stepwise exposure assessment provides information that results in the identification of occupational allergies caused by allergens not included in the European baseline series in a substantial number of patients. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Related Products of 4719-04-4

On October 31, 2021, Aalto-Korte, Kristiina; Pesonen, Maria published an article.Application In Synthesis of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Patterns of positive patch test reactions to formaldehyde and formaldehyde releasers at the F innish I nstitute of O ccupational H ealth from 2007 to 2020. And the article contained the following:

Formaldehyde is an important contact sensitizer. Formaldehyde releasing substances induce pos. reactions in formaldehyde-allergic patients, but there are also reactions independent of formaldehyde allergy. In an earlier study, stronger formaldehyde reactions led to more pos. reactions to quaternium-15. To analyze patterns of pos. patch test reactions to formaldehyde and different formaldehyde releasers. Patch test files of 1497 patients investigated during the period Nov. 2007-August 2020 were retrospectively reviewed for pos. reactions to formaldehyde and its releasers. During the study period, almost all (≥99.3%) patients were tested with a formaldehyde dilution series and six formaldehyde releasers. Ninety-three patients tested pos. to formaldehyde; 80% of these had pos. reactions to at least one formaldehyde releaser, most often benzylhemiformal. There were only nine independent contact allergies to formaldehyde releasers. There were only two reactions to 2-bromo-2-nitropropane-1,3-diol and they occurred in formaldehyde-neg. patients. In patients with extreme (+++) reactions to formaldehyde, concomitant pos. reactions to any of the other 11 investigated formaldehyde releasers were more common than in patients with milder formaldehyde reactions. Strong formaldehyde reactions were associated with pos. reactions to formaldehyde releasers. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application In Synthesis of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

On October 1, 2013, Pizzo, Fabiola; Lombardo, Anna; Manganaro, Alberto; Benfenati, Emilio published an article.Application of 4719-04-4 The title of the article was In silico models for predicting ready biodegradability under REACH: A comparative study. And the article contained the following:

REACH legislation (registration evaluation authorization and restriction of chems.) is an European law to raise the human protection level and environmental health. Under REACH, all manufactured or imported chems. of >1 ton/yr must be evaluated for their ready biodegradability. Ready biodegradability is also used as a screening test for persistent, bioaccumulative, and toxic substances. REACH encourages the use of non-testing methods, e.g.,quant. structure-activity relationship (QSAR) models, to save money and time and reduce the number of animals used for scientific purposes. Some QSAR models are available to predict ready biodegradability. A 722 compound dataset was used to test 4 models: VEGA, TOPKAT, BIOWIN 5 and 6, and START; their performance was compared based on the parameters: accuracy, sensitivity, specificity, and Matthew correlation coefficient Performance was analyzed from different viewpoints. A first calculation was done on the entire dataset; VEGA and TOPKAT had the best accuracy (88% and 87%, resp.). Then compounds inside and outside the training set were considered; BIOWIN 6 and 5 had the best results for accuracy (81%) outside the training set. Another anal. examined the applicability domain (AD); VEGA had the highest value for compounds inside the AD for all parameters considered. Compounds outside the training set and in the model AD were considered to assess predictive ability; VEGA had the best accuracy results (99%) for this group of chems. Generally, the START model had poor results. Since BIOWIN, TOPKAT, and VEGA models performed well, they may be used to predict ready biodegradability. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application of 4719-04-4
