The asymmetric unit of the title compound, C17H17N3O2S, consists of two independent molecules, A and B, with different conformations: in molecule A, the dihedral angles between the central benzene ring and the pendant tolyl and carbamothio-ylhydrazono groups are 71.12 (9) and 5.95 (8)°, respectively. The corresponding angles in molecule B are 50.56 (12) and 26.43 (11)°, respectively. Both molecules feature an intramolecular N - H⋯N hydrogen bond, which closes an S(5) ring. In the crystal, molecules are linked by N - H⋯O, N - H⋯S and C - H⋯O hydrogen bonds, generating a three-dimensional network.
