Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antipsychotic and antidepressant drugs. Its structure supports the formation of bioactive molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry research for modifying pyrrole-based scaffolds to enhance drug potency and selectivity. Also utilized in the preparation of nitro-containing derivatives that can be reduced to amino compounds for further functionalization in drug discovery pathways.
