The title compound, C8H7BrO3, is almost planar (r.m.s. deviation for the non-H atoms = 0.055 angstrom). In the crystal, O-H center dot center dot center dot O hydrogen bonds link the molecules into C(6) chains propagating in [010]. Very weak aromatic pi-pi interactions [centroid-centroid distances = 3.984 (5) and 3.982 (5) angstrom] also occur.
