Irbesartan Impurity 31 CAS 945540-26-1

Description

The occurrence of Irbesartan Impurity 31 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Irbesartan Impurity 31 (CAS 945540-26-1) is a certified pharmaceutical impurity reference standard with the molecular formula C21H20N6O and a molecular weight of 372.42 g/mol.

Based on its molecular formula C21H20N6O, Irbesartan Impurity 31 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 372.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Irbesartan Impurity 31 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.
