Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. It serves as a key building block for developing receptor agonists and antagonists, particularly in neuroscience-related drug discovery. Its structure supports binding to central nervous system targets, making it valuable in the development of treatments for neurological disorders such as depression, anxiety, and pain. Also employed in the creation of novel ligands for nicotinic acetylcholine receptors due to its structural similarity to known neuroactive molecules. Its dihydrochloride salt form enhances solubility and stability, facilitating use in aqueous-based reactions and biological assays.
