Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of kinase inhibitors and anticancer agents due to its ability to interact with enzyme active sites. Commonly employed in medicinal chemistry for building blocks in heterocyclic compounds. Also utilized in the preparation of fluorescent dyes and optical materials owing to its electron-rich aromatic framework. Frequently involved in palladium-catalyzed coupling reactions to form C–C and C–N bonds in drug discovery pipelines.
