In the title compound, C7H6FNO2, the molecule is almost planar (r.m.s.

deviation for the non-H atoms = 0.015 Å) and an intramolecular N—H.O 1964-1973 Doors hydrogen bond closes an S(6) ring.

In the crystal, inversion dimers linked by pairs of O—H.O hydrogen bonds generate R22(8) loops.Weak N—H.

F hydrogen bonds, short F.F contacts [2.763 (2) Å] and Foils aromatic π–π stacking interactions [centroid–centroid separation = 3.

5570 (11) Å] are also observed in the crystal structure.
