Description
As a certified reference material (CRM), Perampanel impurity 41 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 Perampanel impurity 41 (CAS CATO-C4X-243041), a pharmacopoeial impurity reference standard (molecular formula C28H20N2O2, MW 416.47 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C28H20N2O2, Perampanel impurity 41 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 416.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
