Used in pharmaceutical research as a potent serotonin receptor modulator, particularly targeting 5-HT1A receptors. Shows potential in the development of treatments for anxiety, depression, and other central nervous system disorders. Its structure allows for high selectivity and binding affinity, making it a valuable intermediate in synthesizing novel psychoactive drugs. Also investigated for use in positron emission tomography (PET) imaging due to its ability to cross the blood-brain barrier effectively.
