Description
CATO supplies Cenobamate Impurity 51 (CAS CATO-C4X-241651), a pharmacopoeial impurity reference standard (molecular formula C15H23ClN4OSi, MW 338.91 g/mol) used for the identification and quantification of trace impurities in APIs.
Cenobamate Impurity 51 (C15H23ClN4OSi) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), Cenobamate Impurity 51 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.
