Description
As a certified reference material (CRM), Efinaconazole Impurity 11 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 Efinaconazole Impurity 11 (CAS CATO-C4X-124311), a pharmacopoeial impurity reference standard (molecular formula C14H15FN6O2, MW 318.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Efinaconazole Impurity 11 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
