There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(16)O(3)S. 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 a axis by aromatic π-π inter-actions between the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.430 (4) Å] and by additional C-H⋯π and C-H⋯O inter-actions.
标题化合物C(14)H(16)O(3)S的不对称单元中有两个分子。在晶体结构中，羧基参与分子间的O-H⋯O氢键，这些氢键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呋喃环之间的芳香π-π相互作用[质心-质心距离 = 3.430 (4) Å]以及额外的C-H⋯π和C-H⋯O相互作用进一步沿a轴堆积成层。
