The title compound, C14H12N4O4, was prepared by the reaction of 2-nitrophenyl isocyanate with benzoylhydrazine. The dihedral angle between the rings is 71.49 (6)) Å. The molecular conformation is stabilized by an intramolecular N—H⋯O hydrogen bond, generating an S(6) ring. The crystal packing shows N—H⋯O hydrogen bonds.
