In the title compound, C26H27ClN3O3P, the mean plane of the central pyrazole ring forms a dihedral angle of 71.37 (14)° with the chlorophenyl ring. In the crystal, molecules are linked by pairs of N-HO hydrogen bonds, forming inversion dimers with R22(10) ring motifs. The 3-phenyl ring is disordered with four C atoms occupying two sets of sites with an occupancy ratio of 0.748 (4):0.252 (4).
