phenyl)methanone monohydrate, C13H10O4·H2O, two benzene rings are inclined at 44.6 (5)° to each other, and the carbonyl O atom of the benzoyl group lies nearly in the 2,3,4-trihydroxybenzene ring plane. The H atoms of the three hydroxyl groups are oriented in the same direction around the ring and form intra- and intermolecular hydrogen bonds. The crystal structure is stabilized by all of the available hydrogen bonds and by stacking interactions between adjacent molecules.
