On October 31, 2020, Muhialdin, Belal J.; Kadum, Hana; Fathallah, Salahaldin; Meor Hussin, Anis Shobirin published an article.Formula: C8H8O3 The title of the article was Metabolomics profiling and antibacterial activity of fermented ginger paste extends the shelf life of chicken meat. And the article contained the following:

Fermented ginger paste is a traditional condiment in South East Asia used to marinate meat to extend the shelf life and improve the taste. The present study aimed to determine the metabolomics profile of fermented ginger and the effects on the shelf life of chicken meat. Sterilized chicken meat slices were marinated using the fermented and fresh ginger paste and incubated at 8°C to determine the effects on the microbial growth. The bioactive metabolites were identified using 1H NMR based anal. The results demonstrated that fermentation significantly (p<0.05) increased the antibacterial activity of the ginger paste against Salmonella enterica serotype Typhimurium (97%), Listeria monocytogenes (97%) and Staphylococcus aureus (100%), with the microbial load significantly (p < 0.05) reducing to 4.0 and 4.5 Log10 CFU g-1 in the chicken meat slices marinated in fermented ginger. Fermented ginger paste significantly reduced the pH value, moisture content and water activity of chicken meat slices after the incubation for 2 days at 8°C. A total of 25 metabolites were identified in the fermented ginger paste. These results revealed the potential application of fermented ginger paste to enhance the safety of chicken meat via reducing the microbial load. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Formula: C8H8O3

On December 31, 2006, Geier, Johannes; Lessmann, Holger; Becker, Detlef; Bruze, Magnus; Frosch, Peter J.; Fuchs, Thomas; Jappe, Uta; Koch, Patrick; Pfoehler, Claudia; Skudlik, Christoph published an article.Synthetic Route of 4719-04-4 The title of the article was Patch testing with components of water-based metalworking fluids: results of a multicenter study with a second series. And the article contained the following:

Background: Although many allergens in metalworking fluids (MWF) are identified, there are still some MWF components, which are not sufficiently investigated concerning their sensitizing properties. Objectives: To investigate sensitization to 10 frequently used MWF components, which are not part of the established MWF test series, in metalworkers with suspected occupational dermatitis due to MWF. Patients/Methods: Oleyl alc., myristyl alc., dimethylolurea, 4,4′-methylenebis morpholine, imazalil, 1-amino-2-propanol (monoisopropanolamine; MIPA), 2-amino-2-ethyl-1,3-propanediol (AEPD), 2,5-bis(n-octyldithio)-1,3,4-thiadiazole, zinc alkyl dithiophosphate and dibenzyl disulfide have been patch tested in 144 patients. Results: 7 patients reacted pos. to the formaldehyde releaser 4,4′-methylenebis morpholine, and 6 of these patients also reacted to formaldehyde and/or other formaldehyde releasers. 4 Patients reacted pos. to myristyl alc. tested at 10% petrolatum (pet.). Addnl., 20 doubtful or irritant reactions occurred. 1 Patient each reacted pos. to oleyl alc., MIPA, and AEPD. None of the other test substances mentioned above elicited any clear-cut pos. reaction. Patch testing with well-known MWF allergens showed proportions of pos. reactions, which were comparable to those from other studies, e.g. 11% to monoethanolamine, 8% to colophonium and 3%-5% to various preservatives. Conclusions: 4,4′-methylenebis morpholine may be an important MWF allergen, although clin. relevance could not be stated definitely in every case. Myristyl alc. should not be patch tested at 10% pet., but at a lesser concentration, due to irritant properties. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Synthetic Route of 4719-04-4

On July 31, 2016, Li, Xiying; Shi, Bing; Chaikittisilp, Watcharop; Li, Mengmeng; Wang, Yujie; Liu, Yong; Gao, Li; Mao, Liqun published an article.HPLC of Formula: 4719-04-4 The title of the article was A general method to synthesize a family of mesoporous silica nanoparticles less than 100 nm and their applications in anti-reflective/fogging coating. And the article contained the following:

Recent advances in strategies for synthesizing mesoporous silica particle (MSN) have enabled the precise control of its morphol., size, and composition which afford the applications in drug delivery and heterogeneous catalysis. Especially for drug delivery, the size of MSNs <100 nm is a prerequisite allowing for hemolysis effect. However, a general method for the synthesis of MSNs with uniform size distribution <100 nm still remains challenging. Herein, a general method was developed to synthesize a family of aqueous colloidal MSNs with uniform size <100 nm using small organic amines (SOAs) or nitrogen-containing heterocyclic compounds (NCHCs) as alk. catalysts in the presence of cationic quaternary ammonium salts as organic templates. The size of MSNs can be easily adjusted within the range from 28 to 100 nm by the cooperative effect of the mixed alk. catalysts or using different quaternary ammonium surfactants as templates. Also, texture properties of MSNs including pore diameter and surface area were controlled by selecting different kinds of SOAs or NCHCs. Based on the low refractive index of MSNs, these as-prepared MSNs serve as building blocks and afford an anti-reflective/fogging coating on glass slide through a facile dip-coating method. The experimental process involved the reaction of 2,2',2''-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).HPLC of Formula: 4719-04-4

Gannon, J. E.; Adams, M. C.; Bennett, E. O. published an article in 1978, the title of the article was Microbial degradation of diethanolamine and related compounds.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:

Thirteen diethanolamine compounds were tested for their biodegradability employing (1) a bacterium selectively isolated from an industrial cutting fluid, and (2) an acclimatized sewage population obtained from a domestic waste treatment plant. Pure culture growth and BOD studies with the isolate showed that only diethanolamine [111-42-2], methyldiethanolamine [105-59-9], triethanolamine [102-71-6] and lauryl sulfate diethanolamine [72430-24-1] were degradable. BOD techniques using the acclimatized sewage microorganisms as seed yielded similar results with only diethanolamine, methyldiethanolamine, triethanolamine, and lauryl sulfate diethanolamine being oxidized to any meaningful extent. Cyclohexyldiethanolamine [4500-29-2], phenyldiethanolamine [120-07-0], and m-tolyldiethanolamine [91-99-6] had O demands of <1% of their theor. calculated values, while ethyldiethanolamine [139-87-7] and benzyldiethanolamine [101-32-6] accounted for 3.6 and 2.3% of their theor. values, resp.

On February 29, 2008, Steinhauer, K.; Goroncy-Bermes, P. published an article.Application of 4719-04-4 The title of the article was Treatment of water-based metalworking fluids to prevent hypersensitivity pneumonitis associated with Mycobacterium spp.. And the article contained the following:

To prevent further outbreaks of hypersensitivity pneumonitis (HP), biocides are required which are capable of protecting water-based coolants from proliferating mycobacteria. The aim of this study was therefore, to test different biocide preparations on their mycobactericidal activity. Minimal inhibitory concentration values were determined for Mycobacterium chelonae and Mycobacterium immunogenum for triazine-based, methyloxazolidine-based, N/O-formal-based biocidal formulations. All biocides were effective already at a low dosage (<0.05%) irresp. of the presence or absence of organic soiling, except for one N/O-formal-based formulation containing Kathon 886 (CMI). Quenching of CMI in the presence of organic soiling was found to account for loss in efficacy as determined by high-performance liquid chromatog. measurement. Preservation tests were carried out to investigate the efficacy of the biocidal preparations under practical conditions. Results indicate that methyloxazolidine-based biocidal preparations were most effective to prevent coolants from microbial contamination including rapidly growing mycobacteria. Furthermore, it could be demonstrated that common dipslides can be used to easily monitor coolants for contamination by mycobacteria. Our data does not support the hypothesis that mycobacterial proliferation is enhanced by the reduction of competitive microbial population by biocides such as triazines as described earlier but rather suggests a protective effect of biocides regarding mycobacteria in the presence of competitive microbial flora, thereby preventing further outbreaks of HP.

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

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.

On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:

The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2
