Abstract: In the title compound, C₁₁H₁₃N₃O₄S, the thiadiazole ring is nearly planar, while the 1,3-dioxane-4,6-dione ring exhibits a half-chair conformation. The NH group makes one intramolecular contact with a carbonyl group, forming a six-membered ring. The same functional group is involved in an intermolecular N-HN hydrogen bond.
