The title compound, C(11)H(9)FO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-fluoro-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal structure, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further packed into stacks along the b axis by inter-molecular C-H⋯O and C-H⋯F inter-actions.
标题化合物C(11)H(9)FO(3)S是通过2-(5-氟-3-甲基硫基-1-苯并呋喃-2-基)乙酸乙酯的碱性水解制备的。在晶体结构中,羧基参与分子间O-H⋯O氢键,将分子连接成中心对称的二聚体。这些二聚体通过分子间C-H⋯O和C-H⋯F相互作用进一步沿b轴堆积成堆叠结构。
