5-(4-Methylpiperazin-1-yl)-2-nitroaniline

In the title compound, C11H16N4O2, the dihedral angle between the benzene ring and the plane of the four carbon atoms in the piperazine ring is 12.17 (3)°; the latter ring adopts a chair conformation. An intramolecular N—H⋯O hydrogen bond generates an S(6) ring. In the crystal, the molecules are linked by N—H⋯N hydrogen bonds, forming chains.
