The mol­ecule of the title compound, C14H11N3O5, assumes an E configuration with respect to the methyl­idene unit. An intra­molecular O—H⋯O hydrogen bond is present in the mol­ecule. The dihedral angle between the mean planes of the two benzene rings is 5.46 (15)°. The crystal structure is stabilized by inter­molecular O—H⋯O, O—H⋯N, and N—H⋯O hydrogen bonds
