Abstract: The title compound, C12H12FNO3, crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 3-fluoro-4-methyl­phenyl ring and the oxo­amine group is 25.7 (7)° in mol­ecule A and 71.3 (7)° in mol­ecule B, while the mean plane of the 2-methyl­idene-4-oxo­butanoic acid group is twisted by 76.2 (1)° from that of the oxo­amine group in mol­ecule A and by 76.2 (4)° in mol­ecule B. In the crystal, N-H...O and O-H...O hydrogen bonds [the latter forming an R22(8) graph-set motif] link the mol­ecules into a two-dimensional network parallel to the ac plane.
