Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure enables selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. It is also employed in the preparation of fluorescent dyes and optoelectronic materials due to its rigid aromatic framework and electron-deficient nature. Commonly utilized in cross-coupling reactions to build complex molecules for drug discovery and materials science.
