In the title compound, C20H13ClN2O2S, the chlorophenyl, phenyl and thienoyl rings are oriented at dihedral angles 17.84 (7), 53.13 (8) and 34.03 (8)°, respectively, to the central pyrazole ring. An intramolecular O—HO hydrogen bond occurs. In the crystal, pairs of bifurcated O—HO hydrogen bonds link molecules into inversion dimers with R22(12) graph-set motifs.
