In the title compound, C11H15N3O3S, the C-S-N(H)-N linkage is nonplanar, the torsion angle being 75.70 (12)°. The compound has two almost planar fragments linked to the S atom: the hydrazone-derivative fragment [(HONC4H6)N-N(H)-] and the tolyl fragment (C7H7-) have maximum deviations from the mean plane through the non-H atoms of 0.0260 (10) and 0.0148 (14) Å, respectively. The two planar fragments make an interplanar angle of 79.47 (5)°. In the crystal, molecules are connected through inversion centers via pairs of N-HO and O-HN hydrogen bonds.
