Donepezil

Donepezil Impurities

Donepezil impurities include process-related compounds, degradation products, and structurally related analogs formed during synthesis or storage. These are monitored to ensure the safety and efficacy of this acetylcholinesterase inhibitor used in the treatment of Alzheimer’s disease. All materials are structurally confirmed and qualified under ICH guidelines for pharmaceutical analysis and toxicological evaluation.

Donepezil EP Impurities

We offer pharmacopeial and non-pharmacopeial Donepezil impurities that comply with European Pharmacopoeia (EP) specifications. These impurity standards are essential for method development, impurity profiling, and stability testing. Analytical techniques such as HPLC, LC-MS, and NMR are used for their identification and quantification. EP traceable standards are available upon request.

Donepezil Related Compounds

Our catalog includes Donepezil-related compounds such as synthetic intermediates and degradation products. These entries are used in forced degradation studies, impurity identification, and genotoxicity screening. All materials are thoroughly characterized and supported by detailed analytical documentation.

Donepezil Impurity Reference Standards

Donepezil impurity reference standards are supplied with validated analytical data including NMR, MS, and HPLC purity. These materials are used in pharmaceutical R&D, ANDA and DMF filings, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request, and all products meet international regulatory expectations. Supplied materials are re-tested at regular intervals to ensure consistency.
