Description
As a certified reference material (CRM), Valsartan Impurity 94 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 Valsartan Impurity 94 (CAS 1283097-98-2), a pharmacopoeial impurity reference standard (molecular formula C24H27N5O3, MW 433.50 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H27N5O3, Valsartan Impurity 94 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 433.50 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.
