Abstract: In the title compound, C15H14O4, the dihedral angle between the benzene rings is 67.18 (8)°. The Ca-Cm-O-Ca (a = aromatic and m = methylene) torsion angle is 172.6 (3)° and an intramolecular O-HO hydrogen bond generates an S(6) ring. In the crystal, molecules are linked by C-HO hydrogen bonds into zigzag chains propagating in  and C-H interactions also occur.
