In the title compound, C15H13F3O2S, the dihedral angle between the benzene rings is 79.5 (1)°. The ester group is twisted by 7.6 (1)° from the mean plane of the adjacent benzene ring. Disorder was modeled over two sites for one F atom of the trifluoromethyl group with an occupancy ratio of 0.54 (6):0.46 (6). In the crystal, molecules are linked via weak C-HO hydrogen bonds, forming two-dimensional networks lying parallel to (101). The networks are linked via C-H interactions, leading to the formation of a three-dimensional supramolecular structure.
