In the title compound, C(13)H(10)O(3), a benzophenone derivative, the least-squares planes defined by the C atoms of the 2-hy-droxy-phenyl rings inter-sect at an angle of 45.49 (3)°. The substituents on the aromatic systems are both orientated towards the central O atom. Intra- as well as inter-molecular O-H⋯O hydrogen bonds are observed, the latter giving rise to the formation of centrosymmetric dimers. The closest centroid-centroid distance between two π-systems is 3.7934 (7) Å.
