Used as a versatile bifunctional alkylating agent in organic synthesis, particularly in the preparation of cyclic compounds and polymers. Its dual bromo groups enable stepwise nucleophilic substitution reactions, making it valuable in constructing crown ether analogs and other macrocyclic structures. Commonly employed in pharmaceutical intermediates where controlled linker extension is required. Also utilized in material science for crosslinking polymers and modifying surface functionalities due to its reactive terminal bromine atoms. Stable under normal conditions, it facilitates efficient transformations in aprotic solvents like THF or acetonitrile.
