In the title compound, C15H10O5, the cyclopentanone (r.m.s. deviation = 0.049 Å) and oxolane (r.m.s. deviation = 0.048 Å) rings make a dihedral angle of 67.91 (4)°. An intramolecular O—H⋯O hydrogen bond is observed. In the crystal, molecules associate via O—H⋯O hydrogen bonds, forming a three-dimensional network.
