In the title compound, C(11)H(8)ClN(3)O(4), the dihedral angle between benzene and isoxazole rings is 9.92 (1) °. The nitro group is almost coplanar with the benzene ring with an O-N-C-C torsion angle of 8.4 (3)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, closing a six-membered ring.
