Dextromethorphan impurity 41 CAS 1058187-40-8

Description

Compared with other compounds in its class, the molecular weight of 324.26 g/mol gives Dextromethorphan impurity 41 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Dextromethorphan impurity 41 (CAS 1058187-40-8), a pharmacopoeial impurity reference standard (molecular formula C16H21NOHBr, MW 324.26 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Dextromethorphan impurity 41 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Dextromethorphan impurity 41 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.
