Chemical Structure

Lenvatinib Impurity 83 CAS 56766-77-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lenvatinib Impurity 83.

CATO supplies Lenvatinib Impurity 83 (CAS 56766-77-9), a pharmacopoeial impurity reference standard (molecular formula C6H9O4, MW 145.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Lenvatinib Impurity 83 (C6H9O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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 83 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.
