Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its α,β-unsaturated ester structure with a bromine substituent makes it valuable in cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic molecules. Commonly employed in the development of bioactive compounds due to its ability to undergo selective transformations at the double bond or ester group. Also utilized in the synthesis of heterocyclic compounds and functionalized alkenes for research in medicinal chemistry.
