Abstract: In the title compound, C13H11ClO2, the dihedral angle between the mean planes of the 2-chloro­phenyl and phenol rings is 87.4 (9)°. The methyl hy­droxy group lies nearly perpendicular to the plane of its attached benzene ring [O-C-C-C torsion angle = 84.3 (3)°]. The two hy­droxy groups lie on the same side of the mol­ecule and are in a slightly twisted gauche conformation [O-C-C-O torsion angle = 77.1 (8)°] to each other. In the crystal, O-H...O hydrogen bonds between nearby methyl­hydroxy groups form dimers in alternating pairs aligned diagonally along the b axis. A view along the c axis reveals a hexa­meric aggregate mediated by a ring of six O-H...O hydrogen bonds generating an R66(12) motif loop.
