Effect of alkylpyridine structure on the reaction of diphenylphosphinic acid hydrazide with phenyl isothiocyanate was written by Yanchuk, N. I.;Bodrov, V. P.;Tsareva, N. V.. And the article was included in Zhurnal Obshchei Khimii in 1986.SDS of cas: 644-98-4 This article mentions the following:
The catalytic effect of 2-, 3- or 4-methyl-, 2-ethyl-, 2-isopropyl-, 2,4- or 2,6-dimethyl-, and 2,4,6-trimethylpyridine on the rate of Ph2P(O)NHNH2 addition with PhNCS to give Ph2P(O)NHNHCSNHPh was studied. The reaction proceeds via 2 parallel mechanisms, catalytic and noncatalytic. The pyridines with the N atom shielded by alkyl radicals have very low catalytic activity. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4SDS of cas: 644-98-4).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.SDS of cas: 644-98-4
