2-(5-Cyclohexyl-3-methylsulfanyl-1-benzofuran-2-yl)acetic acid

In the title compound, C17H20O3S, the cyclohexyl ring adopts a chair conformation. In the crystal, the carboxyl groups are involved in intermolecular O—H...O hydrogen bonds, which link the molecules into centrosymmetric dimers. These dimers are further stabilized by weak intermolecular C—H...O hydrogen bonds. In addition, the crystal structure also exhibits aromatic π–π interactions between the furan rings of adjacent molecules [centroid–centroid distance = 3.505 (2) Å, interplanar distance = 3.385 (2) Å and slippage = 0.909 (2) Å], and intermolecular C—H...π interactions
