Used in pharmaceutical synthesis as a chiral building block for the production of active pharmaceutical ingredients (APIs), particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of enantiomerically pure compounds, making it valuable in the manufacture of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Also employed in asymmetric synthesis due to its stable amine functionality and rigid indane backbone, which enhance stereoselectivity in catalytic reactions.
