Chemical Structure

Donepezil Impurity 30 CAS CATO-C4X-103930 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 297.31 g/mol gives Donepezil Impurity 30 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Donepezil Impurity 30 (CAS CATO-C4X-103930) is a certified pharmaceutical impurity reference standard with the molecular formula C17H15NO4 and a molecular weight of 297.31 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Donepezil Impurity 30 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Donepezil Impurity 30 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.
