In the title compound C7H9N3O2S the pyrimidine ring shows slight but significant deviations from planarity (X2 = 7.81), the maximum deviation from its best plane being 0.049 (4) Å [C4]. The exocyclic substituents, particularly O1 and O2, deviate appreciably from the pyrimidine plane. Bond distances and angles are normal. There is an intramolecular hydrogen bond between the amino group and the O atom of the formyl group and an intermolecular hydrogen bond between the amino group and the O atom of the ring carbonyl group.
