Used in organic synthesis as a building block for pharmaceuticals and fine chemicals. Acts as a Michael acceptor in conjugate addition reactions due to its α,β-unsaturated ester structure. Employed in the preparation of functionalized intermediates for drug development, particularly in the synthesis of anti-inflammatory and anticancer agents. Also utilized in polymer chemistry to modify resin properties and enhance reactivity in specialty coatings. Its aromatic and vinyl groups allow for further functionalization via cross-coupling or photopolymerization reactions.
