Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry research to build pyrrolopyridine scaffolds, which exhibit a range of biological activities including anti-inflammatory and antiviral properties. Also utilized in solid-phase and solution-phase combinatorial chemistry for drug discovery.
