title: 2-(5-Bromo-3-methyl-sulfinyl-1-benzofuran-2-yl)acetic acid.
abstract: In the title compound, C(11)H(9)BrO(4)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by inter-molecular O-H⋯O and C-H⋯O inter-actions. In addition, the crystal structure exhibits a Br⋯π inter-action of 3.551 (3) Å between the Br atom and the centroid of the benzene ring of an adjacent mol-ecule.
