Used in pharmaceutical research as a key intermediate for synthesizing neuroactive compounds, particularly those targeting central nervous system disorders. Its structure supports the development of agents that modulate neurotransmitter activity, such as serotonin and dopamine pathways. Commonly employed in studies related to anxiety, depression, and cognitive function due to its ability to cross the blood-brain barrier effectively. Also utilized in the preparation of peptidomimetic drugs where enhanced metabolic stability and bioavailability are required.
