Used primarily as a reactive intermediate in organic synthesis, this compound serves as a building block for pharmaceuticals, agrochemicals, and specialty polymers. Its α,β-unsaturated ester structure with a bromine substituent allows for selective nucleophilic substitution and cross-coupling reactions, making it valuable in the preparation of complex molecules. It is also employed in the synthesis of acrylic-based functional materials where controlled reactivity and polymer modification are required. Due to its electrophilic nature, it participates in Michael addition reactions and can be used to introduce ester and vinyl functionalities in heterocyclic and natural product analogs.
