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-HN hydrogen bonds, generating R22(8) loops. This dimer linkage is reinforced by two C-HO hydrogen bonds and one C-HN hydrogen bond.
