CATO supplies n-(2-Fluoro-4-nitrophenyl)methanesulfonamide (CAS 57164-96-2), a certified reference material (molecular formula C7H7FN2O4S, MW 234.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H7FN2O4S, n-(2-Fluoro-4-nitrophenyl)methanesulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
