The three independent mol-ecules of the title compound, C(15)H(14)O(4), have similar orientations of their aromatic rings, the dihedral angles between the rings being 57.0 (1), 58.1 (1) and 58.2 (1)°. In each mol-ecule, the hydr-oxy group forms an intra-molecular hydrogen bond to the carbonyl O atom, forming an S(10) ring motif.
