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

In the title compound, C(17)H(20)O(3)S, 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.
