In the title compound, C13H10O4·H2O, both the carboxylic acid [Car—Car—C—O = −121.1 (2)°, where ar = aromatic] and the ester [Car—Car—O—C = −104.4 (3)°] groups lie out of the mean plane of the conjugated aromatic system. In the crystal, the organic molecule is hydrogen bonded to water molecules through the ester and carboxy moieties, forming chains along thea-axis direction. The methyl H atoms of the acetoxy group are disordered over two equally occupied sites.
