Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of indole-based derivatives, which are common in medicinal chemistry. Commonly employed in the creation of serotonin receptor ligands and other neuroactive agents. Also applied in research settings for the design of novel compounds with potential antidepressant or antipsychotic activity. Serves as a building block in the synthesis of more complex heterocyclic systems due to its functionalized indole core.
