Used primarily in pharmaceutical research as a key intermediate in the synthesis of nicotinic acetylcholine receptor (nAChR) modulators. It serves as a structural scaffold in the development of compounds targeting neurological disorders such as Alzheimer's disease, Parkinson's disease, and schizophrenia. Its rigid bicyclic framework enhances selectivity and binding affinity to specific receptor subtypes, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in the creation of ligands for positron emission tomography (PET) imaging to study receptor distribution in the brain.
