Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocycles for drug discovery. Also employed in materials science for creating organic semiconductors and fluorescent dyes due to its extended aromatic system and electron-deficient nature. Common in cross-coupling reactions like Suzuki and Buchwald-Hartwig to build complex molecules for research and industrial applications.
