Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for carbon-chain elongation and functional group transformations due to the reactivity of both the bromine atom and the double bond. Commonly employed in coupling reactions, such as Suzuki or Heck reactions, to construct more complex molecules. Also utilized in the synthesis of specialty polymers and fine chemicals where selective reactivity is required. Its vinyl bromide functionality makes it valuable in palladium-catalyzed reactions for forming carbon-carbon bonds.
