Abstract: The title compound, C₁₂H₁₁ClO₄S, was prepared by the oxidation of methyl 2-(5-chloro-3-methylsulfanyl-1-benzofuran-2-yl)acetate with 3-chloroperoxybenzoic acid. The O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic - interactions between the benzene rings of neighbouring molecules [centroid-to-centroid distance = 3.809 (2) Å], and by C-H interactions between a methyl H atom and the furan ring of an adjacent molecule. In addition, the crystal structure exhibits intermolecular C-HO hydrogen bonds.
