Used in the synthesis of pharmaceutical intermediates, particularly in the development of serotonin receptor modulators. Serves as a building block in the preparation of bioactive molecules with potential antidepressant and anxiolytic properties. Employed in research settings for constructing fluorinated indole derivatives to study structure-activity relationships in central nervous system-targeting drugs. Also applied in the design of novel kinase inhibitors due to the electron-withdrawing effect of the fluorine atom enhancing binding affinity.
