Used primarily in pharmaceutical research as a key intermediate in the synthesis of nicotinic acetylcholine receptor (nAChR) modulators. It plays a significant role in the development of compounds targeting neurological disorders such as Alzheimer's disease, Parkinson's disease, and schizophrenia. Due to its structural affinity for neural receptors, it is also explored in the design of antidepressants and cognitive enhancers. Its hydrochloride salt form improves solubility and stability, making it suitable for in vitro and in vivo studies. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity of central nervous system (CNS) agents.
