Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules, particularly in the development of antiviral and anticancer agents. Employed in cross-coupling reactions, such as Suzuki and Heck reactions, to construct complex quinoxaline derivatives. Also applied in materials science for the synthesis of organic semiconductors and fluorescent dyes due to its aromatic and electron-deficient structure.
