Bupropion Impurity 56 CAS 80478-43-9 chemical structure

Description

CATO manufactures Bupropion Impurity 56 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.

Bupropion Impurity 56 (CAS 80478-43-9) is a certified pharmaceutical impurity reference standard with the molecular formula C13H20ClNOHCl and a molecular weight of 278.22 g/mol.

Bupropion Impurity 56 (C13H20ClNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
