The title compound, C16H12O4, exists as planar molecules in the solid state (r.m.s. deviation of 0.02 Å in one molecule and 0.07 Å in the second independent molecule comprising the asymmetric unit). In each molecule, the 1-hydroxy group forms an intramolecular hydrogen bond to the adjacent carbonyl O atom.
