Azilsartan impurity 140 CAS CATO-C4X-1096140

Description

Compared with other compounds in its class, the molecular weight of 445.47 g/mol gives Azilsartan impurity 140 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Azilsartan impurity 140 (CAS CATO-C4X-1096140), a pharmacopoeial impurity reference standard (molecular formula C24H23N5O4, MW 445.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Azilsartan impurity 140 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 445.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 140 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.
