In the mol-ecular structure of the title compound, C(12)H(9)BrO(2), the methoxy-carbonyl group is twisted by a dihedral angle of 29.8 (3)°with respect to the naphthalene ring system. An overlapped arrangement is observed between parallel naphthalene ring systems of adjacent mol-ecules, and the face-to-face distance of 3.590 (9) Å suggests there is π-π stacking in the crystal structure.
