Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves as a building block in the production of selective receptor modulators, including serotonin and dopamine receptor ligands. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for optimizing drug potency, selectivity, and pharmacokinetic properties. Commonly employed in research and development of antidepressants, antipsychotics, and cognitive enhancers.
