Used as a key intermediate in the synthesis of functional polymers and specialty resins, particularly in the development of high-performance thermosetting materials. Its reactive maleimide group enables participation in Michael addition reactions and radical polymerizations, making it valuable in creating crosslinked networks for coatings, adhesives, and composites with enhanced thermal and chemical resistance. Also employed in the modification of proteins and biomolecules for research applications due to its selective reactivity with thiol and amine groups. Additionally, it serves as a building block in the preparation of pharmaceuticals and agrochemicals where aromatic and imide functionalities are required.
