Used in pharmaceutical research as a key intermediate in the synthesis of nicotinic acetylcholine receptor (nAChR) modulators. It serves as a structural scaffold for developing compounds targeting neurological disorders such as Alzheimer's, Parkinson's, and schizophrenia. Its spirocyclic framework enhances metabolic stability and blood-brain barrier penetration, making it valuable in CNS drug design. Also explored in the development of smoking cessation aids due to its affinity for nicotinic receptors.
