The compound consists of a 1,2,4-triazole heterocycle with three functional groups: amine, thioamide, hydrazide. X-ray crystallography shows that this molecule is polar but with a C=S double bond. It is prepared by the reaction of hydrazine with thiourea:[1] 2 SC(NH2)2 + 3 N2H4 → SC2N3H(NH2)(N2H3) + 4 NH3 + H2S The compound has been used as a reagent for the colorimetric detection of aldehydes.[2] References1. ^N.
