Chemical Structure

Memantine Impurity 32 CAS 16267-35-9 chemical structure

Description

As a process- or degradation-related impurity, Memantine Impurity 32 (CAS 16267-35-9, C12H20) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an organic framework, Memantine Impurity 32 is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 164.29 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 Memantine Impurity 32 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.
