Description
As a certified reference material (CRM), Nebivolol Impurity 91 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 Nebivolol Impurity 91 (CAS CATO-C4X-196891), a pharmacopoeial impurity reference standard (molecular formula C29H37F2NO8, MW 565.60 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C29H37F2NO8, Nebivolol Impurity 91 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 565.60 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).
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.
