Used in organic synthesis as an intermediate for pharmaceutical compounds, particularly in the development of indole-based bioactive molecules. Its structure supports the construction of nitrogen-containing heterocycles, which are common in drugs targeting neurological and inflammatory conditions. The nitro group allows for further functionalization, enabling derivatization for medicinal chemistry research. Commonly employed in the synthesis of potential kinase inhibitors and serotonin receptor modulators. Also utilized in the preparation of fluorescent probes due to the indole scaffold’s photophysical properties.
