Oseltamivir Impurity 162 CAS CATO-C4X-1720162

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Oseltamivir Impurity 162.

Oseltamivir Impurity 162 (CAS CATO-C4X-1720162) is a certified pharmaceutical impurity reference standard with the molecular formula C16H26N4O4 and a molecular weight of 338.40 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Oseltamivir Impurity 162 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.40 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 162 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.
