Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Also employed in materials science for the preparation of organic semiconductors and fluorescent probes due to its electron-deficient aromatic core. Commonly utilized in cross-coupling reactions such as Suzuki and Buchwald-Hartwig to form C–C and C–N bonds in advanced synthetic pathways.
