Used in organic synthesis as a bifunctional building block, particularly in the preparation of macrocyclic compounds and long-chain derivatives. The bromine terminus allows for nucleophilic substitution or coupling reactions, while the carboxylic acid group enables amide or ester formation. Commonly employed in the development of specialty polymers, surface modifiers, and in medicinal chemistry for linker construction in prodrugs or bioconjugates. Its long aliphatic chain supports membrane interaction studies and is useful in synthesizing lipid-like structures for biochemical research.
