The asymmetric unit of the title compound, C15H13FN2O, contains two independent mol­ecules with different conformations; the two aromatic rings in the independent mol­ecules form dihedral angles of 85.3 (2) and 10.0 (2)°. In the crystal, N—H...O hydrogen bonds link the mol­ecules into chains along [100].

In the title compound, C9H7NO6, the dihedral angles between the benzene ring and its three substituents are 29.99 (8)° for the nitro, 67.09 (8)° for the carb­oxy and 32.48 (10)° for the meth­oxy­carbonyl group. In the crystal, one classical O—H...O and two nonclassical C—H...O contacts link adjacent mol­ecules, forming a three-dimensional structure.
