Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. The bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic and alkenyl systems. The vinyl bromide moiety is particularly useful in forming carbon-carbon bonds under palladium catalysis. Its styrenyl structure with a brominated alkene side chain makes it suitable for polymer modification and development of specialty materials. Also employed in the synthesis of bioactive molecules where the bromine serves as a leaving group or a site for further functionalization.
