Chemical Structure

Azilsartan Impurity 174 CAS 2382294-55-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 185.01 g/mol gives Azilsartan Impurity 174 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Azilsartan Impurity 174 (CAS 2382294-55-3) is a certified pharmaceutical impurity reference standard with the molecular formula C5H6Cl2O3 and a molecular weight of 185.01 g/mol.

The molecular framework of Azilsartan Impurity 174 (C5H6Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Azilsartan Impurity 174 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.
