In the title compound, C18H12O4, the essentially planar chromenone ring system [the maximum deviation = 0.016 (2) Å] is nearly co-planar with the phenyl ring [dihedral angle = 3.85 (8)°]. An intramolecular O—H...O hydrogen bond occurs. In the crystal, weak C—H...O hydrogen bonds and π–π stacking interactions link the molecules into a three-dimensional supramolecular network
