Used as a reactive diluent and crosslinking agent in polymer formulations, particularly in unsaturated polyester resins and coatings. Enhances curing efficiency and improves the mechanical and thermal properties of the final product. Employed in the synthesis of specialty monomers and copolymers due to its ability to undergo Michael addition and free radical polymerization. Also utilized in the development of adhesives and sealants where low viscosity and good reactivity are required. Acts as a building block in organic synthesis for pharmaceuticals and agrochemicals, leveraging its electron-deficient double bond for nucleophilic attack.
