In the title compound, C12H11FO4S, the O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment [O-S-C-C and C-S-C-C torsion angles = 126.70 (13) and -123.55 (13)°, respectively]. The crystal structure is stabilized by weak non-classical intermolecular C-HO hydrogen-bond interactions. The crystal structure also exhibits aromatic - stacking interactions between furan/benzene and benzene/benzene rings of adjacent benzofuran ring systems [centroid-centroid distances = 3.8258 (9) and 3.8794 (9) Å] and a weak intermolecular C-H ring interaction.
