Used in research as a selective agonist for nicotinic acetylcholine receptors, particularly the α4β2 subtype. It is employed in studies related to neurodegenerative diseases such as Alzheimer's and Parkinson's, helping to investigate cognitive function, memory, and neuroprotection. Also utilized in addiction research, especially for understanding nicotine dependence mechanisms. Its high selectivity makes it valuable in developing potential therapeutics targeting cholinergic pathways.
