In the title compound, C(17)H(16)O(3), the dihedral angle between the aromatic rings is 4.59 (7)° and an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, adjacent mol-ecules are linked by C-H⋯O hydrogen bonds, leading to the formation of [001] supra-molecular chains. Weak C-H⋯π inter-actions consolidate the packing.
