Used primarily as a key intermediate in organic synthesis, this compound is valuable for introducing functionalized ester and bromomethyl groups into complex molecules. Its reactivity makes it suitable for radical bromination reactions and cross-coupling processes. It is often employed in the preparation of pharmaceuticals, agrochemicals, and specialty polymers due to its ability to undergo nucleophilic substitution and cyclization reactions. The presence of both a bromide and an activated double bond allows for sequential transformations, enabling the construction of carbon-carbon and carbon-heteroatom bonds in multi-step synthetic routes.
