Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 408.45 g/mol gives Roxadustat Impurity 147 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Roxadustat Impurity 147 (CAS CATO-C4X-2213147), a pharmacopoeial impurity reference standard (molecular formula C23H24N2O5, MW 408.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C23H24N2O5, Roxadustat Impurity 147 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 408.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Roxadustat Impurity 147 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.
