Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its α,β-unsaturated ester structure makes it suitable for Michael addition reactions and cross-coupling reactions, especially in the development of bioactive molecules. Commonly employed in the preparation of liquid crystals, agrochemicals, and functional materials due to the presence of the bromoaryl group, which allows further functionalization via palladium-catalyzed reactions. Also utilized in research settings for constructing conjugated systems in organic electronic materials.
