Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.55 g/mol gives Lumefantrine Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Lumefantrine Impurity 9 (CAS 7061-81-6, C13H7Cl3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Lumefantrine Impurity 9 (C13H7Cl3) contains chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Lumefantrine Impurity 9 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.
