Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules targeting cancer and inflammatory diseases. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Also employed in the preparation of fluorescent probes and organic semiconductors due to its electron-deficient aromatic core. Commonly utilized in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds in drug discovery pipelines.
