Osman, F. H.; El-Hamouly, W. S.; Abdel-Gawad, M. M.; Abbasi, M. M. published an article in 1982, the title of the article was The behavior of 2,2′-(tert-butylimino)diethanol toward five-membered heterocycles containing phosphorus(III).Safety of 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:

The reaction of 2,2′-(tert-butylimino)diethanol Me3CN(CH2CH2OH)2 (I) with dioxaphospholanes II (X = Cl, NMe2) gave III. Thermal reaction of III with I gives a complete rearrangement yielding a mixture of spirophosphorane IV, V, and traces of another product. III reacts with Ph azide to give a mixture of penta- and tetracoordinated phosphorus structures VI and VII, resp. Biacetyl condenses with III to give VIII. Reaction of dioxaphospholane IX (X = Cl) with I yields a mixture of the biphosphite V and another product believed to be either triethylammonium tris(o-phenylenedioxy) phosphate or spirobenzodioxaphospholane X. Similarly, dioxaphospholane IX (X = NMe2) reacts with I forming a mixture of XI and XII. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Safety of 2,2′-(tert-Butylazanediyl)diethanol

On June 30, 1987, Robert, Dominique; Gawad, Hoda Abdel; Riess, Jean G. published an article.SDS of cas: 2160-93-2 The title of the article was Fluorophosphoranes as Lewis acids. The conditions of access to hexacoordinated neutral adducts via the intramolecular addition of an electron donor. And the article contained the following:

The preparation of bicyclic neutral hexacoordinated fluorophosphorus adducts (I) from RPF4 (R = F, Me, Ph) and (Me3SiOCH2CH2)2X (X = O, S, NH, NMe, NCMe3, NPh) was examined Adduct I was formed predominantly only in the case where R = F and X = S. In all the other cases there was a strong tendency to form ionic species. The 8-membered dialkoxyfluorophosphorane model precursor II (X = CH2) does not form easily, and the driving force towards the formation of the very stable RPF5- anions and of tetracoordinated phosphorylated species leads to its easy decomposition The monocyclic adducts of type III and IV are not easier to prepare: compound V only could be obtained where X = NH2 and R = F, while the spirophosphorane VI was isolated when R = Ph. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

Iriondo, Aitziber; Agirre, Ion; Viar, Nerea; Requies, Jesus published an article in 2020, the title of the article was Value-added bio-chemicals commodities from catalytic conversion of biomass derived furan-compounds.Synthetic Route of 111-29-5 And the article contains the following content:

A review. The depletion of fossil resources in the near future and the need to decrease greenhouse gas emissions lead to the investigation of using alternative renewable resources as raw materials. One of the most promising options is the conversion of lignocellulosic biomass (like forestry residues) into bioenergy, biofuels and biochems. Among these products, the production of intermediate biochems. has become an important goal since the petrochem. industry needs to find sustainable alternatives. In this way, the chem. industry competitiveness could be improved as bioproducts have a great potential market. Thus, the main objective of this review is to describe the production processes under study (reaction conditions, type of catalysts, solvents, etc.) of some promising intermediate biochems., such as; alcs. (1,2,6-hexanetriol, 1,6-hexanetriol and pentanediols (1,2 and 1,5-pentanediol)), maleic anhydride and 5-alkoxymethylfuran. These compounds can be produced using 5-hydroxymethylfurfural and/or furfural, which they both are considered one of the main biomass derived building blocks. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Synthetic Route of 111-29-5

On August 18, 2020, Ozdemir, Ozgun O.; Soyer, Ferda published an article.Related Products of 621-37-4 The title of the article was Pseudomonas aeruginosa Presents Multiple Vital Changes in Its Proteome in the Presence of 3-Hydroxyphenylacetic Acid, a Promising Antimicrobial Agent. And the article contained the following:

Pseudomonas aeruginosa, a widely distributed opportunistic pathogen, is an important threat to human health for causing serious infections worldwide. Due to its antibiotic resistance and virulence factors, it is so difficult to combat this bacterium; thus, new antimicrobial agents are in search. 3-Hydroxyphenylacetic acid (3-HPAA), which is a phenolic acid mostly found in olive oil wastewater, can be a promising candidate with its dose-dependent antimicrobial properties. Elucidating the mol. mechanism of action is crucial for future examinations and the presentation of 3-HPAA as a new agent. In this study, the antimicrobial activity of 3-HPAA on P. aeruginosa and its action mechanism was investigated via shot-gun proteomics. The data, which are available via ProteomeXchange with identifier PXD016243, were examined by STRING anal. to determine the interaction networks of proteins. KEGG Pathway enrichment anal. via the DAVID bioinformatics tool was also performed to investigate the metabolic pathways that undetected and newly detected groups of the proteins. The results displayed remarkable changes after 3-HPAA exposure in the protein profile of P. aeruginosa related to DNA replication and repair, RNA modifications, ribosomes and proteins, cell envelope, oxidative stress, as well as nutrient availability. 3-HPAA showed its antimicrobial action on P. aeruginosa by affecting multiple bacterial processes; hence, it could be categorized as a multitarget antimicrobial agent. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Related Products of 621-37-4

On September 15, 2022, Lu, Yunhao; Yang, Linzi; An, Yunfeng; Liu, Dayu; Yang, Guohua; He, Qiang published an article.Electric Literature of 473-81-4 The title of the article was Salt tolerance and ester production mechanisms of Candida etchellsii in Chinese horse bean-chili-paste. And the article contained the following:

Candida etchellsii is a predominant strain in Chinese horse bean-chili-paste, a famous and traditional condiment with high salt content. In this study, physiol. properties, ester production capacity and gene expression of C. etchellsii under salt stress were investigated, and the results showed that the strain evoked miscellaneous regulations to resist high salt stress. Under salt stress, C. etchellsii would accumulate intracellular glycerol, Na+ and K+ to balance osmotic pressure. Interestingly, the strain showed much stronger capacity to yield Et hexanoate and hexyl acetate after 5% and 20% (w/v) NaCl treatment whether in esterification or alcoholysis system. Furthermore, transcriptome data indicated that the genes associated with carbohydrate metabolism and amino acid metabolism had significantly different expression, and their regulations were consistent with the results of physiol. anal. The results obtained in this study could contribute to understand the salt tolerance mechanism of C. etchellsii and provide a theor. support for its application in traditional food fermentation The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Electric Literature of 473-81-4

On April 9, 2020, Yang, Xingchuan; Wei, Genlei; Chen, Xiangmeng; Xu, Li; Liu, Guoji published an article.Application of 111-29-5 The title of the article was Liquid-Liquid Equilibrium Measurement and Correlation for the Ternary Systems (Dimethyl Succinate + 1,4-Butanediol)/(Dimethyl Glutarate + 1,5-Pentanediol)/(Dimethyl Adipate + 1,6-Hexanediol) + Water at Different Temperatures. And the article contained the following:

Liquid-liquid equilibrium (LLE) data for esters + diols + water ternary systems were measured at 101.3 kPa at four different temperatures, namely, 293.15, 303.15, 313.15, and 323.15 K. The Othmer-Tobias equation and the Hand equation were applied to examine the reliability of the LLE data in which both regression coefficients were higher than 0.98. The calculated distribution coefficients and separation factors were larger than 1, which means that it is feasible to extract the diols from the corresponding ester with water. In addition, NRTL and UNIQUAC models were applied to correlate the exptl. data, and the binary interaction parameters were obtained. The calculated root-mean-square deviation values show that both models are in good agreement with the exptl. data. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Application of 111-29-5
