Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its α,β-unsaturated carbonyl structure makes it suitable for Michael addition reactions and other conjugate additions, enabling the construction of complex molecules. Employed in the synthesis of bioactive compounds, including antimicrobial and antitumor agents, due to its ability to act as an electrophilic building block. Also utilized in the development of specialty polymers and as a reagent in cross-coupling reactions where the bromine functionality allows for further functionalization via palladium-catalyzed processes.
