Chemical Structure
Description
As a certified reference material (CRM), Donepezil Impurity 49 Trifluoroacetate 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 Donepezil Impurity 49 Trifluoroacetate (CAS CATO-C4X-103949), a pharmacopoeial impurity reference standard (molecular formula C24H29NO4C2HF3O2, MW 509.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H29NO4C2HF3O2, Donepezil Impurity 49 Trifluoroacetate contains a steroid core, 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 509.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
