In the title compound, C15H16O3, enantiomeric pairs of molecules form centrosymmetric dimers by mutual hydrogen bonding of carboxyl groups, with the ketone not involved in the hydrogen bonding. The plane of the carboxyl group [O(2)-C(11)-O(3)] makes a dihedral angle of 86.3 (2)° with the plane of the ketone {O(1)-C(10)[-C(1)-C(6)]}. The observed C-O bond lengths and angles in the carboxyl group are equivalent due to disorder. There is a reciprocal intermolecular 2.570 (4) Å contact between the aromatic H(14 A) and the ketone O atom [O(1)].
