Description
CATO supplies Oseltamivir Impurity 80 (CAS CATO-C4X-1720180), a pharmacopoeial impurity reference standard (molecular formula C22H38N2O9HCl, MW 511.01 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Oseltamivir Impurity 80 (C22H38N2O9HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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 manufactures Oseltamivir Impurity 80 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
