Used as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a building block for creating complex molecules due to its reactive double bond and ester functionalities. Commonly employed in Michael addition reactions and other carbon-carbon bond-forming processes. Its tert-butyl group provides steric bulk, which can influence selectivity in reactions, making it valuable in the development of chiral compounds and active pharmaceutical ingredients (APIs). Also utilized in polymer chemistry as a monomer or cross-linking agent to modify material properties.
