Compared with other compounds in its class, the molecular weight of 406.39 g/mol gives Lumefantrine Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lumefantrine Impurity 11 (CAS CATO-C4X-242611) is a certified pharmaceutical impurity reference standard with the molecular formula C23H29Cl2NO and a molecular weight of 406.39 g/mol.
Based on its molecular formula C23H29Cl2NO, Lumefantrine Impurity 11 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 406.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Lumefantrine Impurity 11 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.
