Used in pharmaceutical synthesis as an intermediate for developing central nervous system agents, particularly in the production of selective norepinephrine reuptake inhibitors. It plays a key role in creating compounds that modulate neurotransmitter activity, making it valuable in the research and development of antidepressants and anxiolytic drugs. Its structure allows for effective binding and selectivity in neurochemical pathways, enhancing drug efficacy. Commonly employed in late-stage functionalization during medicinal chemistry optimization.
