Axitinib Impurity 42 CAS 808142-24-7

Description

The occurrence of Axitinib Impurity 42 is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Axitinib Impurity 42 (CAS 808142-24-7), a pharmacopoeial impurity reference standard (molecular formula C39H32O3P2, MW 610.62 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C39H32O3P2, Axitinib Impurity 42 contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 610.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Axitinib Impurity 42 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.
