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 R 2 2(8) graph-set motif] link the molecules into a two-dimensional network parallel to the ac plane.
