In the title compound, C 8 H 9 N 5 O, the mean planes through the pyrimidine and triazine rings form a dihedral angle of 2.83 (16)°. The amino group adopts a trigonal-planar configuration and forms an intra­molecular resonance-assisted N—H⋯O=C hydrogen bond with the carbonyl group. In the crystal, mol­ecules are linked  via  inter­molecular N—H⋯N hydrogen bonds into chains of  C22 (6)[ R22 (6)] motif. The molecules form two types of sheet parallel to (201) and (    01), respectively.
