In the title compound, C15H11BrO3, the dihedral angle between the benzene rings is 72.59 (6)°. In the crystal, pairs of C—Hπ contacts form inversion dimers. Additional C—HO hydrogen bonds generate R21(6) ring motifs and stack these dimers along the b axis. Short intermolecular BrO contacts of 3.254 (3) Å are also observed and link the stacks into a three-dimensional network.
