Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It reacts readily with amines and alcohols to form amides and esters, making it valuable in constructing complex molecules. Commonly employed in the preparation of benzoxazepines and other heterocyclic compounds with biological activity. Also utilized in peptide coupling and in the development of functionalized polymers. Its bromine substituent allows for further modification via cross-coupling reactions such as Suzuki or Heck reactions, expanding its utility in medicinal chemistry and materials science.
