Chemical Structure
Description
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.
N,N,1,2-tetramethyl-1H-imidazole-4-sulfonamide (CAS 936083-53-3) is a high-purity analytical reference standard with the molecular formula C7H13N3O2S and a molecular weight of 203.26 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, N,N,1,2-tetramethyl-1H-imidazole-4-sulfonamide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
