In the title compound, C10H9N3O3S, the five-membered ring adopts a slightly twisted conformation about the Cm—S (m = methylene) bond. The dihedral angle between this ring and the benzene ring is 7.99 (9)°. A bifurcated intramolecular N—H(O,S) hydrogen bond helps to establish the near planar conformation of the molecule. In the crystal, molecules are linked by N—HO and O—HO hydrogen bonds to generate (001) sheets.
