Dextromethorphan Impurity 14 (Mixture of Rotamers) CAS 29144-31-8 chemical structure

Description

CATO manufactures Dextromethorphan Impurity 14 (Mixture of Rotamers) 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.

CATO supplies Dextromethorphan Impurity 14 (Mixture of Rotamers) (CAS 29144-31-8), a pharmacopoeial impurity reference standard (molecular formula C18H23NO2, MW 285.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H23NO2, Dextromethorphan Impurity 14 (Mixture of Rotamers) 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 285.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
