Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methanesulfonamide, N-[2-fluoro-4-(isothiocyanatomethyl)phenyl]- (CAS 565448-37-5), molecular formula C9H9FN2O2S2 and molecular weight 260.31 g/mol, is a CATO reference standard with documented purity and traceability.
Methanesulfonamide, N-[2-fluoro-4-(isothiocyanatomethyl)phenyl]- (C9H9FN2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Methanesulfonamide, N-[2-fluoro-4-(isothiocyanatomethyl)phenyl]- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
