Used primarily in research and development, particularly in the study of muscarinic acetylcholine receptors. It acts as a selective antagonist, helping to understand receptor function and signaling pathways in the nervous system. Its application extends to pharmacological studies aiming to develop treatments for conditions like Alzheimer's disease, Parkinson's disease, and other neurological disorders. Additionally, it is utilized in biochemical assays to explore the effects of receptor blockade on cellular responses.
