Used as a key intermediate in organic synthesis, particularly in the preparation of macrocyclic compounds and lactones. Its bifunctional nature—containing both a bromine and a carboxylic acid group—allows for sequential reactions, such as nucleophilic substitution followed by cyclization. Commonly employed in the synthesis of functionalized polymers and specialty esters for fragrances and pharmaceuticals. Also utilized in the development of surface modifiers for nanoparticles due to its ability to anchor to metal surfaces through the carboxylic group while the bromine end provides a site for further chemical attachment.
