Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly those targeting neurological and psychiatric disorders. Its structure supports the development of agents that modulate serotonin receptors, making it valuable in the research of antidepressants and anxiolytics. Also employed in the preparation of biologically active oxindole derivatives with potential anticancer and anti-inflammatory properties. Commonly utilized in medicinal chemistry for constructing complex heterocyclic systems found in natural products and drug candidates.
