Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and anticancer agents. Its α,β-unsaturated ester structure makes it valuable in Michael addition reactions and other conjugate additions in organic synthesis. Also employed in the preparation of agrochemicals and functionalized polymers due to its reactivity and ability to undergo cross-coupling reactions. Commonly utilized in research settings for constructing complex molecules through palladium-catalyzed transformations and cyclization processes.
