Crystal structure of 1H-1,2,4-triazole-3-mercaptoacetic acid, C4H5N3O2S

Synthesis and in vitro antimicrobial activity of new 4-phenyl-5-methyl-4H-1,2,4-triazole-3-thione derivatives

“…In this paper the reaction of this compound with ethyl bromoacetate was investigated (2). Basing on the results of the previous papers, the elemental and spectral analysis as well as on the X-ray crystallography of similar compound, it was revealed and confirmed that the reaction leads to the formation of S-derivative 21 . Reaction with ethyl bromoacetate in presence of sodium ethanolate gave ethyl [(4-phenyl-5-methyl-4-H-1,2,4-triazol-3-yl)sulfanyl] acetate (2), which was converted to hydrazide (3) in reaction with 100% hydrazine hydrate.…”
