Compared with other compounds in its class, the molecular weight of 710.82 g/mol gives Candesartan Cilexetil Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Candesartan Cilexetil Impurity 17 (CAS 856414-35-2) is a certified pharmaceutical impurity reference standard with the molecular formula C45H38N6O3 and a molecular weight of 710.82 g/mol.
The molecular framework of Candesartan Cilexetil Impurity 17 (C45H38N6O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Candesartan Cilexetil Impurity 17 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.
