Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.62 g/mol gives Norepinephrine Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Norepinephrine Impurity 37 (CAS CATO-C4X-151437, C8H9NO3HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Norepinephrine Impurity 37 (C8H9NO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Norepinephrine 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.
