The title compound, C(13)H(13)FO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-fluoro-3-isopropyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal, the carb-oxy 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 a slipped π-π inter-action between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.727 (2) Å, inter-planar distance = 3.465 (2) Å and slippage = 1.373 (2) Å]. The crystal structure also exhibits a short S⋯O contact [S⋯O = 3.219 (2) Å].
标题化合物C(13)H(13)FO(3)S是通过2-(5-氟-3-异丙基硫烷基-1-苯并呋喃-2-基)乙酸乙酯的碱性水解制备的。在晶体中,羧基参与分子间O-H⋯O氢键作用,将分子连接成中心对称的二聚体。这些二聚体通过相邻分子的呋喃环和苯环之间的滑移π-π相互作用进一步沿b轴堆积成堆叠结构[质心-质心距离 = 3.727 (2) Å,平面间距离 = 3.465 (2) Å,滑移 = 1.373 (2) Å]。晶体结构还表现出短的S⋯O接触[S⋯O = 3.219 (2) Å]。
