Abstract: The asymmetric unit of the title compound C25H19N5OS, contains two mol­ecules, A and B. In mol­ecule A, the dihedral angles between the pyrazole ring and the C-bound phenyl group, the N-bound phenyl group and the thia­diazole ring are 32.30 (14), 52.25 (14) and 34.94 (12)°, respectively. The corresponding angles in mol­ecule B are 33.32 (14), 50.67 (15), and 70.30 (12)°, respectively. In the crystal, the A and B mol­ecules are linked by pairs of N-H...N hydrogen bonds, generating R22(8) loops. This dimer linkage is reinforced by two C-H...O hydrogen bonds and one C-H...N hydrogen bond.
