Chemical Structure
Description
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.
CATO supplies Peramivir Impurity 53 (CAS CATO-C4X-183353), a pharmacopoeial impurity reference standard (molecular formula C18H32N2O4, MW 340.46 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Peramivir Impurity 53 (C18H32N2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Peramivir Impurity 53 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.
