In the title compound, C7H6F3NO2, all the non-H atoms except for one of the F atoms lie on a crystallographic mirror plane. In the crystal, the molecules are linked into inversion dimers by pairs of C-HF interactions, forming R22(10) loops. These dimers are connected into C(6) chains along  through N-HO hydrogen bonds. Aromatic - stacking interactions [centroid-centroid separation = 3.8416 (10) A°] connect the molecules into a three-dimensional network.
