Description
CATO supplies Docetaxel Impurity 62 (CAS CATO-C4X-161962), a pharmacopoeial impurity reference standard (molecular formula C43H53NO14, MW 807.88 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C43H53NO14, Docetaxel Impurity 62 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 807.88 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), Docetaxel Impurity 62 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.
