Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for creating analogs in drug discovery programs targeting cancer and inflammatory diseases. The aldehyde group allows for further functionalization via reactions such as reductive amination or Wittig chemistry, enabling rapid diversification of molecular scaffolds. Also utilized in the preparation of pyrrolopyridine-based compounds with potential antiviral or neuroprotective activity.
