Description
CATO supplies Paliperidone Impurity 91 (CAS CATO-C4X-172491), a pharmacopoeial impurity reference standard (molecular formula C23H24F2N4O3, MW 442.46 g/mol) used for the identification and quantification of trace impurities in APIs.
Paliperidone Impurity 91 (C23H24F2N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
CATO manufactures Paliperidone Impurity 91 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.
