Chemical Structure
Description
The occurrence of Benazepril Impurity 13 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benazepril Impurity 13 (CAS CATO-C4X-209613) is a certified pharmaceutical impurity reference standard with the molecular formula C24H27N3O6 and a molecular weight of 453.49 g/mol.
Based on its molecular formula C24H27N3O6, Benazepril Impurity 13 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 453.49 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.
As a certified reference material (CRM), Benazepril Impurity 13 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.
