Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 617.05 g/mol gives Lenvatinib Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lenvatinib Impurity 11 (CAS 2613141-84-5) is a certified pharmaceutical impurity reference standard with the molecular formula C31H29ClN6O6 and a molecular weight of 617.05 g/mol.
Lenvatinib Impurity 11 (C31H29ClN6O6) 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. 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).
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 Lenvatinib 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.
