Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides due to its reactive imide structure and halogenated aromatic ring. Its electron-deficient alkene group enables participation in Diels-Alder and Michael addition reactions, making it valuable in polymer chemistry for modifying resins and enhancing thermal stability. Also employed in the preparation of specialty monomers for high-performance polymers and functional materials.
