In the title molecule, C12H8F3NO3, the trifluoromethyl group is rotationally disordered over three orientations in a 0.5:0.3:0.2 ratio. In the crystal, N—H
O hydrogen bonds link the molecules related by translation into chains along the c axis. The crystal packing exhibits π–π interactions between the pyran rings of neighboring molecules [centroid–centroid distance = 3.462 (4) Å] and short CO contacts of 3.149 (4) Å.
