Summary: | In the title compound, C8H3F4NO3, the carboxy group lies nearly in the plane of the ring with a C—C—C—O torsion angle of −10.5 (4)°. The carbamoyl group is almost perpendicular to the benzene ring [C—C—C—O torsion angle = 82.2 (4) °]. In the crystal, molecules are linked via O—H...O and N—H...O hydrogen bonds involving the carbamoyl and carboxy groups. |
