In the title mol-ecule, C(16)H(16)BrN(5)O(3)S, the 1,3,4-thia-diazole ring is situated under the benzene ring, forming a dihedral angle of 86.6 (2)°, and with an S⋯Cg (where Cg is the centroid of the benzene ring) distance of 3.312 (3) Å. The benzene and 1,3,4-thia-diazole rings form dihedral angles of 83.8 (3) and 57.7 (2)°, respectively, with the central pyrazole ring. In the absence of classical hydrogen bonds, the crystal packing is stabilized by a C-H⋯π inter-action..
