Description
As a certified reference material (CRM), N-Nitroso Vilanterol impurity 57 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 N-Nitroso Vilanterol impurity 57 (CAS 3085658-79-0), a pharmacopoeial impurity reference standard (molecular formula C24H32Cl2N2O6, MW 515.43 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H32Cl2N2O6, N-Nitroso Vilanterol impurity 57 contains a flavonoid core, 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 515.43 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.
