Makarskii, V. V. published the artcileQuantum-chemical analysis of tautomerism of 1,2,4-triazole and its amino and diamino derivatives, SDS of cas: 63598-71-0, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1977), 540-5, database is CAplus.
The heats of formation and dipole moments of I, II, and their 3-amino and 3,5-diamino derivatives were calculated by CNDO/2 and MINDO/2 methods. The unsym. triazole rings were favored over the sym. rings, and exocyclic amino tautomers were favored over imino tautomers.
Khimiya Geterotsiklicheskikh Soedinenii published new progress about 63598-71-0. 63598-71-0 belongs to triazoles, auxiliary class Triazole, name is 4H-1,2,4-Triazole, and the molecular formula is C2H3N3, SDS of cas: 63598-71-0.
