In the the title compound, C27H23ClN4O2, the chlorophenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O—H...O hydrogen bond generates an S(8) ring motif. The molecules are linked into chains running along the c axis by N—H...N hydrogen bonds, and the chains are cross-linked via C—H...O hydrogen bonds and C—H...π interactions involving the chlorophenyl ring.
