Compared with other compounds in its class, the molecular weight of 259.34 g/mol gives Amorolfine Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Amorolfine Impurity 37 (CAS CATO-C4X-154237), a pharmacopoeial impurity reference standard (molecular formula C16H21NO2, MW 259.34 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C16H21NO2, Amorolfine Impurity 37 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 259.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Amorolfine Impurity 37 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.
