The whole molecule of the title compound, C16H18O4, is generated by twofold rotational symmetry; the twofold axis bisects the central C—C bond. The O—C—C—O torsion angle about the central C—C bond is 69.45 (16)°. Symmetry-related benzene rings are inclined to one another by 64.91 (8)°. In the crystal, molecules are connected by C—HO hydrogen bonds, forming a three-dimensional network.
