Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 187.67 g/mol gives Metaraminol Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Metaraminol Impurity 17 (CAS 54779-56-5), a pharmacopoeial impurity reference standard (molecular formula C9H13NOHCl, MW 187.67 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Metaraminol Impurity 17 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Metaraminol Impurity 17 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.
