In the title compound, C28H24F6N2O3, the mean plane of the central pyrazoline ring forms dihedral angles of 2.08 (9) and 69.02 (16)° with the 2-benzyloxy-6-hydroxy-4-methylphenyl and 3,5-bis(trifluoromethyl)phenyl rings, respectively. The dihedral angle between the mean planes of the pyrazoline and 3,5-bis(trifluoromethyl)phenyl rings is 68.97 (9)°. An intramolecular O-HN hydrogen bond is observed, which forms an S(6) graph-set motif. In the crystal, pairs of weak C-HF halogen interactions link the molecules into inversion dimers while molecular chains along  are formed by C-HO contacts.
