Abstract: In the title compound, C10H11N3O2, the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 3.4 (3)°] and forms an intramolecular N-HO hydrogen bond with the amine group. In the crystal, weak aromatic C-HO and C-HN hydrogen bonds link the molecules. Weak aromatic ring - interactions [minimum ring centroid-centroid separation = 3.9841 (16) Å] are also present.
