The asymmetric unit of the title compound, C8H7ClO2, consists of two independent molecules, with comparable geometries. Both molecules are approximately planar (r.m.s. deviations = 0.040 and 0.064 Å for the 11 non-H atoms). In the crystal, molecules are linked via intermolecular O—H⋯O and C—H⋯O hydrogen bonds into chains two molecules thick along (-101).
