Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for the synthesis of heterocyclic compounds due to its reactive α,β-unsaturated carbonyl structure and bromine functionality. Commonly employed in condensation reactions and cyclization processes to form coumarins, flavonoids, and other biologically active molecules. Also utilized in the development of dyes and fragrances for its ability to undergo selective transformations. Its electrophilic nature makes it suitable for Michael addition reactions in the production of fine chemicals.
