Description
As a certified reference material (CRM), Carfilzomib Impurity 97 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.
CATO supplies Carfilzomib Impurity 97 (CAS CATO-C4X-102297), a pharmacopoeial impurity reference standard (molecular formula C120H173N15O21Cl, MW 2197.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C120H173N15O21Cl, Carfilzomib Impurity 97 contains a nitrogen-containing heterocyclic scaffold, 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 2197.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
