Chemical Structure
Description
Based on its molecular formula F2NO4S2C6H11N2, 3-Ethyl-1-methyl-1H-imidazol-3-ium Bis(fluorosulfonyl)amide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 291.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 3-Ethyl-1-methyl-1H-imidazol-3-ium Bis(fluorosulfonyl)amide (CAS 235789-75-0), a certified reference material (molecular formula F2NO4S2C6H11N2, MW 291.29 g/mol) for analytical method development and quality control.
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.
