The title compound, C11H16N4O3 [6-amino-1,3-dimethyl-5-(4-oxo-2-penten-2-yl)amino-2,4(1H,3H)-pyrimidinedione], shows extensive delocalization in the uracil ring. There is an intramolecular hydrogen bond [N
O 2.713 (3) Å] between an amino N—H group and an adjacent carbonyl O atom. The molecules are linked into sheets that are parallel to the (10
) plane by intermolecular N-HO hydrogen bonds [NO 2.805 (3) and 2.803 (3) Å].
