Description
As a certified reference material (CRM), Trandolapril EP Impurity E (Trandolaprilate) 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 Trandolapril EP Impurity E (Trandolaprilate) (CAS 87679-71-8), a pharmacopoeial impurity reference standard (molecular formula C22H30N2O5, MW 402.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H30N2O5, Trandolapril EP Impurity E (Trandolaprilate) contains a flavonoid 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 402.48 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.
