Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor (nAChR) modulators. It plays a critical role in creating compounds targeting neurological disorders such as Alzheimer's disease, Parkinson's disease, and cognitive dysfunction. Its structure allows for selective binding and improved bioavailability in central nervous system agents. Commonly employed in medicinal chemistry for constructing potent and selective drug candidates, especially in smoking cessation therapies and treatments for neuropathic pain.
