Used primarily in organic synthesis as an intermediate for constructing complex molecules, particularly in the development of pharmaceuticals and bioactive compounds. The bromine functional group allows for further chemical modifications through cross-coupling reactions, such as Suzuki or Heck reactions, enabling the formation of carbon-carbon bonds. Its long aliphatic chain makes it suitable for studies involving lipid analogs, membrane permeability, and fatty acid metabolism. Also employed in the preparation of specialty polymers and surfactants where precise chain length and functionalization are required.
