Used in organic synthesis as a key intermediate for pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the formation of biologically active heterocyclic compounds. Commonly employed in medicinal chemistry for constructing fused pyrrolopyridine scaffolds, which are found in several drug candidates targeting cancer and inflammatory diseases. Also utilized in research settings for designing new small-molecule therapeutics due to its reactivity and ability to form stable derivatives.
