Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 420.42 g/mol gives Azilsartan Impurity 124 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Azilsartan Impurity 124 (CAS CATO-C4X-1096124) is a certified pharmaceutical impurity reference standard with the molecular formula C22H20N4O5 and a molecular weight of 420.42 g/mol.
The molecular framework of Azilsartan Impurity 124 (C22H20N4O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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 Azilsartan Impurity 124 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.
