چکیده
In the title mol-ecule, C(12)H(13)N(5)O(2)S, a bifurcated intra-molecular N-H⋯O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36 (11)° with the pyrazole ring. In the crystal, pairs of N-H⋯S hydrogen bonds form centrosymmetric dimers, generating R(2) (2)(8) ring motifs, which stack along the b axis.
