Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. Shows potential in the development of central nervous system agents due to its structural features that interact with neurotransmitter receptors. Its derivatives are explored for antidepressant and antipsychotic activity. Also employed in medicinal chemistry for structure-activity relationship studies, particularly in optimizing compounds targeting monoamine transporters. The fumarate salt form enhances stability and solubility, making it suitable for formulation development in early-stage drug discovery.
