Chemical Structure

Oseltamivir Impurity 123 CAS CATO-C4X-1720123 chemical structure

Description

Oseltamivir Impurity 123 (CAS CATO-C4X-1720123) is a certified pharmaceutical impurity reference standard with the molecular formula C16H28O5 and a molecular weight of 300.39 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Oseltamivir Impurity 123 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.39 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.

CATO manufactures Oseltamivir Impurity 123 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.
