Used in the synthesis of pharmaceutical intermediates, particularly in the development of serotonin receptor modulators. Acts as a building block in the preparation of bioactive molecules with potential antidepressant and antipsychotic activities. Also employed in the construction of fluorinated indole derivatives for research in medicinal chemistry, where the fluorine atom enhances metabolic stability and binding affinity. Commonly utilized in cross-coupling reactions and condensation processes to form complex heterocyclic systems.
