The asymmetric unit of the title compound, C14H10O4, contains one half molecule, the complete molecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11 (5)°. Intermolecular O-HO hydrogen bonds link the molecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supramolecular layers by weak - stacking interactions between neighbouring benzene rings, with centroid-centroid distances of 3.7648 (8) Å.
