Used primarily in pharmaceutical research as an intermediate in the synthesis of selective receptor modulators. It plays a role in developing compounds targeting central nervous system disorders, particularly serotonin and dopamine receptor ligands. Its structure supports binding affinity and selectivity, making it valuable in the design of potential antipsychotic and antidepressant agents. Also explored for use in positron emission tomography (PET) tracer development due to its ability to cross the blood-brain barrier and engage specific neural targets.
