Description
CATO supplies Cenobamate Impurity 54 (CAS 1233712-93-0), a pharmacopoeial impurity reference standard (molecular formula C16H14O3, MW 254.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Cenobamate Impurity 54 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.28 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.
As a certified reference material (CRM), Cenobamate Impurity 54 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.
