Used primarily 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 formation of fused heterocyclic systems that are common in drug design, especially for anticancer and anti-inflammatory agents. The compound's reactivity allows for selective functionalization, making it valuable in medicinal chemistry for building complex nitrogen-sulfur containing scaffolds. It is also employed in research settings to explore new pathways in heterocyclic chemistry and to develop novel therapeutic candidates.
