Abstract: Molecules of the title compound, C₁₈H₁₆O₆, are almost planar. The dihedral angle between the benzopyran system and the benzene ring is 3.36 (5)°. In addition to an intramolecular O-HO hydrogen bond, molecules are connected by weak intermolecular C-HO hydrogen bonds to form a two-dimensional framework.
