In the title compound, C14H9F3O2S, the dihedral angle between the mean planes of the benzene rings is 88.7 (2)°. The carb-oxy-lic acid group is twisted by 13.6 (7)° from the mean plane of its attached aromatic ring. One of the F atoms of the tri-fluoro-methyl group is disordered over two sites in a 0.61 (7):0.39 (7) ratio. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(8) loops. Weak C-H⋯F inter-actions are also observed.
在标题化合物C₁₄H₉F₃O₂S中，苯环平均平面之间的二面角为88.7 (2)°。羧酸基团与其相连芳环的平均平面扭转了13.6 (7)°。三氟甲基中的一个氟原子在两个位置上无序，比例为0.61 (7):0.39 (7)。在晶体中，通过O—H⋯O氢键对连接的反演二聚体形成R 2 (2)(8)环。还观察到弱的C—H⋯F相互作用。
