In the title compound, C16H12Br2O6·C2H5OH, the two benzene rings are twisted by 80.64 (5)° and the carboxyl groups form dihedral angles of 72.48 (3) and 89.41 (2)° with the corresponding benzene rings. In the crystal structure, the biphenyl molecules are connected by intermolecular O—H⋯O and O—H⋯Br hydrogen bonds, resulting in a chain along the b axis.
