The asymmetric unit of the title compound, C(18)H(11)Br(2)ClO(3), contains two crystallographically independent mol-ecules in which the dihedral angles between the naphthalene ring systems and the benzene rings are 55.64 (11) and 60.50 (11)°. In each mol-ecule, an intra-molecular O-H⋯O=C hydrogen bond generates a six-membered ring. In the crystal structure, inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds and two different Br⋯O halogen bonds [2.9850 (19) and 3.2169 (19) Å] are observed.
