Used primarily as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its α,β-unsaturated ester structure with an iodine substituent makes it valuable in cross-coupling reactions, such as Heck, Suzuki, and Sonogashira reactions, enabling the formation of complex organic frameworks. It is also employed in the synthesis of functionalized acrylic derivatives and heterocyclic compounds. Due to its reactivity, it serves in research settings for constructing carbon-carbon bonds and introducing acrylate functionality in conjugated systems.
