Chemical Structure

Telmisartan Impurity 52 CAS 7356-11-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 195.17 g/mol gives Telmisartan Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Telmisartan Impurity 52 (CAS 7356-11-8) is a certified pharmaceutical impurity reference standard with the molecular formula C9H9NO4 and a molecular weight of 195.17 g/mol.

Based on its molecular formula C9H9NO4, Telmisartan Impurity 52 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.17 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).

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.

CATO manufactures Telmisartan Impurity 52 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.
