Used in pharmaceutical research as an intermediate in the synthesis of bioactive compounds, particularly those targeting neurological and psychiatric disorders. Its structure supports the development of agents with potential antidepressant and anxiolytic effects. Also explored in the design of serotonin receptor modulators due to its carbazole backbone, which is known for favorable interactions with central nervous system targets. Additionally, it serves as a building block in the preparation of more complex heterocyclic systems for drug discovery.
