Chemical Structure
Description
The occurrence of 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-sulfonamide is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-sulfonamide (CAS 5338-86-3) is a high-purity analytical reference standard with the molecular formula C4H5N3O4S and a molecular weight of 191.17 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
