title: 2-(5-Bromo-3-isopropyl-sulfanyl-1-benzofuran-2-yl)acetic acid.
abstract: The title compound, C(13)H(13)BrO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-bromo-3-isopropyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into dimers. These dimers are further packed into stacks along the c axis by inter-molecular C-H⋯π inter-actions, and by slipped π-π inter-actions between the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.472 (2) Å, inter-planar distance = 3.398 (2) Å and slippage = 0.713 (2) Å].
