Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 501.83 g/mol gives Lumefantrine impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Lumefantrine impurity 7 (CAS CATO-C4X-24267), a pharmacopoeial impurity reference standard (molecular formula C26H23Cl3N2O2, MW 501.83 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C26H23Cl3N2O2, Lumefantrine impurity 7 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 501.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 7 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.
