In the title compound, C15H10BrClO3S, the 4-bromo-substituted benzene ring forms a dihedral angle of 72.55 (6)° with the mean plane [mean deviation = 0.008 (2) Å] of the benzofuran ring system. In the crystal, molecules are linked by weak C—H⋯O hydrogen bonds into chains along . There are also π–π interactions between the furan and benzene rings of symmetry-related benzofuran systems [centroid–centroid distances = 3.549 (3) and 3.632 (3) Å].
