In the title compound, C14H11NO4, the dihedral angle between the mean planes of the aromatic rings is 3.96 (12)° and an intramolecular O—H...O hydrogen bond closes anS(6) ring. A short intramolecular C—H...O contact is also seen. In the crystal, carboxylic acid inversion dimers linked by pairs of O—H...O hydrogen bonds generateR22(8) loops. Conversely, the N—H group does not form a hydrogen bond. Aromatic π–π interactions exist at a centroid–centroid distance of 3.8423 (15) Å between the benzene rings. An extremely weak C—H...π interaction also is present.
