Chemical Structure

Irbesartan Impurity 24 CAS CATO-C4X-166624 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

Irbesartan Impurity 24 (CAS CATO-C4X-166624) is a certified pharmaceutical impurity reference standard with the molecular formula C25H28N6O and a molecular weight of 428.53 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Irbesartan Impurity 24 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
