Azilsartan Impurity N2 CAS 1675221-59-6

Description

Compared with other compounds in its class, the molecular weight of 430.45 g/mol gives Azilsartan Impurity N2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Azilsartan Impurity N2 (CAS 1675221-59-6), a pharmacopoeial impurity reference standard (molecular formula C25H22N2O5, MW 430.45 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C25H22N2O5, Azilsartan Impurity N2 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 430.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Azilsartan Impurity N2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
