Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure enables functionalization at multiple sites, 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 aromatic and electron-deficient nature. Additionally, it serves as a building block in agrochemicals for designing novel pesticides and herbicides.
