Used in pharmaceutical research as a key intermediate in the synthesis of selective receptor modulators, particularly for central nervous system agents. Its structure supports binding to specific neurotransmitter receptors, making it valuable in developing compounds for neurological and psychiatric disorders. Commonly employed in the creation of experimental drugs targeting serotonin and dopamine pathways. Also utilized in radiolabeled forms for positron emission tomography (PET) imaging studies to track receptor occupancy in the brain.
