Used primarily in neuroscience research as a selective antagonist for α7 nicotinic acetylcholine receptors. It helps in studying the role of these receptors in cognitive functions, memory, and neurodegenerative diseases like Alzheimer's. Also employed in investigations of pain pathways and psychiatric disorders such as schizophrenia. Due to its high specificity, it is valuable in receptor binding assays and electrophysiological studies. Not used in clinical medicine; strictly for laboratory research.
