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 suitable for Michael addition reactions and cyclization processes. Commonly employed in the synthesis of heterocyclic compounds and as a building block for introducing ester and vinyl bromide functionalities in complex molecules. Also utilized in the development of bioactive compounds due to its reactivity in palladium-catalyzed coupling reactions.
