Description
As a certified reference material (CRM), Flecainide EP Impurity F 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.
CATO supplies Flecainide EP Impurity F (CAS CATO-C4X-25463), a pharmacopoeial impurity reference standard (molecular formula C18H22F6N2O3, MW 428.37 g/mol) used for the identification and quantification of trace impurities in APIs.
Flecainide EP Impurity F (C18H22F6N2O3) contains a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
