Chemical Structure
Description
Difluoromethanesulfonamide (CAS 50585-74-5), molecular formula CH3F2NO2S and molecular weight 131.10 g/mol, is a CATO reference standard with documented purity and traceability.
Difluoromethanesulfonamide (CH3F2NO2S) contains a sulfone group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
