The title compound, C12H17N3OS, crystallizes with two independent molecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the benzene ring and the hydrazinecarbothioamide group are 6.9 (4) and 37.2 (5)° in molecules A and B, respectively. An intramolecular O—H...N hydrogen bond is observed in each molecule. This serves to maintain an approximately planar conformation for molecule A, but leaves a significant twist between these two groups in molecule B. In the crystal, a weak N—H...S interaction is observed, forming inversion dimers among the B molecules and resulting in an R22(8) motif. These dimers are further interconnected by weak N—H...O and C—H...O intermolecular interactions, forming chains along [011].
