Chemical Structure

Lenvatinib Impurity 31 CAS 417722-95-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 463.87 g/mol gives Lenvatinib Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lenvatinib Impurity 31 (CAS 417722-95-3), a pharmacopoeial impurity reference standard (molecular formula C24H18ClN3O5, MW 463.87 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C24H18ClN3O5, Lenvatinib Impurity 31 contains a flavonoid 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 463.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Lenvatinib Impurity 31 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
