title: 2-Hydrazinyl-4-methyl-1,3-benzothia-zole.
abstract: The title compound, C(8)H(9)N(3)S, is almost planar (r.m.s. deviation = 0.019 Å) apart from the terminal -NH(2) grouping [deviation of the N atom = 0.286 (2) Å]. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating (001) sheets.
