Chemical Structure

Azilsartan Impurity 43 CAS 1514933-24-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Azilsartan Impurity 43.

CATO supplies Azilsartan Impurity 43 (CAS 1514933-24-4), a pharmacopoeial impurity reference standard (molecular formula C27H26N4O6, MW 502.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C27H26N4O6, Azilsartan Impurity 43 contains a steroid 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 502.52 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.

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 43 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.
