Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 473.49 g/mol gives Capecitabine Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Capecitabine Impurity 22 (CAS CATO-C4X-102422), a pharmacopoeial impurity reference standard (molecular formula C21H32FN3O8, MW 473.49 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H32FN3O8, Capecitabine Impurity 22 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 473.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Capecitabine Impurity 22 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.
