In the title compound, C(15)H(10)BrFO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-bromo-phenyl ring is rotated out of the benzofuran plane [dihedral angle = 38.98 (8)°], while the structure is stabilized by an inter-molecular C-H⋯O hydrogen bond and a Br⋯O halogen bond [3.036 (2) Å] and has an inter-molecular C-H⋯π inter-action between the 4-bromo-phenyl H atom and the benzene ring of an adjacent benzofuran mol-ecule, as well as aromatic π-π inter-actions between the benzene rings of the benzofuran systems [centroid-centroid distance = 3.482 (3) Å].
