Design and syntheses of some new pyrazolo[3,4-d]-8-(phenyl)-1,2,4-(8H)-triazolo-[2,3-a]-pyrimidin-4(1H)-one derivatives as potent anti-inflammatory agent was written by Kawade, D. P.;Khedekar, P. B.. And the article was included in World Journal of Pharmacy and Pharmaceutical Sciences in 2014.Safety of 2,4-Dichlorophenylisothiocyanate This article mentions the following:
Pyrazolo[3,4-d](aryl)-1,2,4-triazolopyrimidinones I [R = 2-Me, 4-Me, 2-Cl, 4-Cl, 2-O2N, 4-O2N, etc.] were synthesized from 5-amino-6-arylamino-6,7-dihydro-1H-pyrazolo[3,4-d]pyrimidin-4-ones which were obtained by the reaction of ethyl-5-amino-1H-pyrazole-4-carboxylate and appropriate phenylisothiocyanate in the presence of toluene followed by cyclization reaction with hydrazine hydrate in absolute ethanol. The most active compounds I [R = 2-O2N, 4-O2N] were evaluated for its ulcerogenicity. The results of anti-inflammatory activity (in-vivo) indicated that the compounds I [R = 2-O2N, 4-O2N] possessed significant anti-inflammatory activity as compared to standard drug, Indomethacin. In the experiment, the researchers used many compounds, for example, 2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1Safety of 2,4-Dichlorophenylisothiocyanate).
2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Safety of 2,4-Dichlorophenylisothiocyanate
