Abstract: In the title compound, C16H12O4, the substituent benzene ring and methoxy group are twisted relative to the 4H-chromene skeleton by 24.1 (1) and 61.3 (1)°, respectively. In the crystal, molecules are connected by classical O-HO and weak C-HO hydrogen bonds, forming chains parallel to . The 4H-chromene ring systems of adjacent molecules are either parallel or inclined at an angle of 28.9 (1)°.
