Used as an intermediate in organic synthesis, particularly in the preparation of long-chain functionalized fatty acid derivatives. Its bromine functionality allows for further coupling reactions, such as in the formation of macrocyclic compounds or in the extension of carbon chains via nucleophilic substitution or metal-catalyzed cross-coupling reactions. Commonly employed in the development of bioactive molecules, including potential pharmaceuticals or agrochemicals, where a long aliphatic spacer with a terminal functional group is required. Also useful in polymer chemistry for introducing long alkyl chains into polymer backbones or side chains, modifying material properties such as flexibility, hydrophobicity, or thermal stability.
