Lenvatinib Impurity 32 CAS 205448-64-2

Description

Compared with other compounds in its class, the molecular weight of 335.31 g/mol gives Lenvatinib Impurity 32 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lenvatinib Impurity 32 (CAS 205448-64-2), a pharmacopoeial impurity reference standard (molecular formula C16H17NO7, MW 335.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Lenvatinib Impurity 32 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Lenvatinib Impurity 32 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.
