Abstract: In the title compound, C₁₇H₁₂O₄, the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the molecules in the crystal structure is governed by C-HO and O-HO hydrogen-bonding interactions.
