In the title compound, C15H11NO4, the dihedral angle formed by the benzene ring and the essentially planar 2-benzofuran ring system is 55.93 (3)°. In the crystal, intermolecular O—H...O hydrogen bonds link pairs of molecules, generating centrosymmetric R22(8) ring motifs. These dimeric units are connected via N—H...O hydrogen bonds, forming C(6) chains along [100].
