Abstract: In the title compound, C12H16N4O3, all bond lengths and angles are within normal ranges. An O-HN and an N-HO intramolecular hydrogen bond contribute to the approximately planar molecular conformation. In the crystal structure, intermolecular N-HO and N-HN hydrogen bonds link the molecules into ribbons parallel to the  direction.
