Chemical Structure
Description
1-(Carboxymethyl)-3-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (CAS 671793-16-1), molecular formula C2F6NO4S2C6H9N2O2 and molecular weight 421.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(Carboxymethyl)-3-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 421.28 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.
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.
