The title compound, C10H8O3, aggregates in the crystal structure as catemers, whose hydrogen bonding progresses from the carboxyl to the ketone of a neighboring screw-related molecule along the b axis [O⋯O = 2.6481 (12) Å and O - H⋯O = 169°]. Four hydrogen-bonding chains in centrosymmetric pairs pass through the cell in the b-axis direction. Two intermolecular C - H⋯O=C close contacts are found, involving both the ketone and acid functions.
