Description
CATO manufactures Rimegepant Impurity 119 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.
CATO supplies Rimegepant Impurity 119 (CAS CATO-C4X-2487119), a pharmacopoeial impurity reference standard (molecular formula C19H31NO2Si, MW 333.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Rimegepant Impurity 119 (C19H31NO2Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
