Description
CATO manufactures Norepinephrine Impurity 84 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 Norepinephrine Impurity 84 (CAS CATO-C4X-151484), a pharmacopoeial impurity reference standard (molecular formula C24H21NO9, MW 467.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Norepinephrine Impurity 84 (C24H21NO9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
