Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based drugs. Its nitro group allows for further functionalization, enabling the production of amines or other derivatives important in medicinal chemistry. Commonly employed in research settings for constructing complex heterocyclic systems found in bioactive molecules. Also utilized in the preparation of selective kinase inhibitors and serotonin receptor modulators due to the indole scaffold’s prevalence in such agents.
