Used primarily as a reactive monomer in polymer synthesis, enabling the production of specialty acrylic resins with enhanced crosslinking properties. Its α,β-unsaturated carbonyl structure allows participation in Michael addition reactions and Diels-Alder cycloadditions, making it valuable in organic synthesis for building complex molecules. Employed in coatings and adhesives to improve curing speed and film hardness due to its high electrophilicity. Also serves as a key intermediate in pharmaceuticals and agrochemicals synthesis, where its ester and vinyl functionalities permit selective modifications. Limited use in fragrance and flavor applications as a building block for ester derivatives, though handling requires caution due to potential irritant properties.
