CATO supplies Encorafenib Impurity 6 (CAS CATO-C4X-32496), a pharmacopoeial impurity reference standard (molecular formula C19H23ClFN7, MW 403.88 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Encorafenib Impurity 6 (C19H23ClFN7) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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. 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 Encorafenib Impurity 6 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.
