Used in pharmaceutical synthesis as a key intermediate for developing central nervous system agents, particularly in the production of antidepressants and antipsychotic drugs. Its rigid bicyclic structure with a fluorine substituent enhances binding selectivity to certain neurotransmitter receptors. Commonly employed in medicinal chemistry for optimizing metabolic stability and bioavailability in drug candidates. Also utilized in the preparation of radiolabeled compounds for positron emission tomography (PET) imaging studies targeting brain receptors.
