Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure supports the construction of fused heterocyclic systems that are common in drug discovery. It is also employed in research settings for the preparation of pyrrolopyridine derivatives, which show potential in medicinal chemistry for treating inflammatory diseases, cancer, and central nervous system disorders. Additionally, it serves as a building block in combinatorial chemistry and library synthesis for high-throughput screening.
