In the title compound, C14H12O2, the benzene rings make a dihedral angle of 58.84 (12)°. In the crystal, molecules are linked into chains along the b-axis direction by O—H⋯O hydrogen bonds. These chains are further linked by C—H⋯O hydrogen bonds, forming layers parallel to the bc plane.

The title compound was synthesized by Fries rearrangement. 3-Methylphenylbenzoate was treated with anhydrous aluminium chloride (0.002 mol) as a catalyst at 150–170 °C under without solvent condition for about 2–3 h. Then the reaction mixture was cooled to room temperature and quenched with 6 N HCl in the presence of ice water. The reaction mixture was stirred for about 2–4 h, and the solid was filtered and recrystallized with acetonitrile to obtain the title compound.
All H-atoms were located in a difference map and then were positioned geometrically (C—H = 0.93–0.96 Å and O—H = 0.82 Å). They were refined using a riding model with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O, Cmethyl) .

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Benzophenone and related compounds have a wide variety of biological activities such as anti-fungal and anti-inflammatory (Khanum et al., 2004; Selvi et al., 2003). The presence of various substituents in the benzophenone nucleus is essential to determining the quantitative structure-activity relationships of these systems. The competence of benzophenones as chemotherapeutic agents, especially as inhibitors of HIV-1 reverse transcriptase RT, cancer and inflammation, is well established and their chemistry has been studied extensively. In addition, methyl-substituted benzophenones exhibit chemotherapeutical activity against fungi. Some studies were carried out to show that methyl-substituted benzophenones exhibit anti-fungal properties (Naveen et al., 2006). In view of its extensive background, the title compound was prepared and characterized by single-crystal X-ray diffraction.
In the molecular structure of the title compound (Fig. 1), bond lengths and angles do not show large deviations and are comparable with those reported for a similar structure (Mahendra et al., 2005). The dihedral angle between the two benzene rings (C1–C6) and (C9–C16) is 58.84 (12)°. The crystal structure is stabilized by intermolecular C—H···O and O—H···O hydrogen bonds (Table 1 & Fig. 2).
