Used as a linker molecule in organic synthesis, particularly in the preparation of macrocyclic compounds and polymers. Its terminal bromine atoms readily undergo nucleophilic substitution, enabling the connection of two reactive units in step-growth polymerizations. Commonly employed in the synthesis of functionalized materials, including conjugated systems for electronic applications and crosslinking agents in specialty resins. Also utilized in the fabrication of molecular tethers and spacers in supramolecular chemistry due to its well-defined chain length.
