In the title compound, C(21)H(13)BrO(4)S·C(6)H(6), the O atom and the phenyl group of the phenyl-sulfinyl substituent are located on opposite sides of the mean plane of the 5,6-methyl-enedioxy-benzofuran fragment; the phenyl ring is almost perpendicular to this plane [83.66 (6)°]. The 4-bromo-phenyl ring is rotated slightly out of the 5,6-methyl-enedioxy-benzo-furan plane, making a dihedral angle of 2.9 (1)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds and inter-molecular C-H⋯π inter-actions. The crystal structure also exhibits π-π inter-actions between the benzene ring and the 4-bromo-phenyl ring of an adjacent mol-ecule [centroid-centroid distance = 3.586 (3) Å].
