The asymmetric unit of the title compound, C11H10N6O3S, contains two independent molecules, each of which is stabilized by an intramolecular N—H⋯O hydrogen bond, forming an S(6) ring motif. In one molecule, the pyrazole ring forms a dihedral angle of 10.93 (14)° with the benzene ring. The corresponding dihedral angle in the other molecule is 7.03 (14)°. In the crystal, molecules are linked via pairs of (N,N)—H⋯O bifurcated acceptor bonds which, together with C—H⋯O hydrogen bonds, form sheets parallel to (001).
