In the title compound, C18H11Br2ClO3, an intramolecular O—HO=C hydrogen bond occurs, forming a six-membered ring. The naphthalene ring system and the benzene ring make a dihedral angle of 57.36 (9)°. The central carbonyl C—(C=O)—C group is twisted away from the naphthalene ring system and the benzene ring by 18.61 (15) and 26.25 (16)°, respectively. In the crystal structure, two intermolecular BrCl close contacts [3.4927 (7) and 3.4325 (7) Å] are observed.
