Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Also employed in materials science for designing organic semiconductors and fluorescent probes due to its rigid aromatic framework and electron-deficient character. Commonly utilized in cross-coupling reactions such as Suzuki and Buchwald-Hartwig to build complex molecules for research and industrial applications.
