Used as a key intermediate in the synthesis of macrocyclic compounds, particularly in the preparation of crown ether analogs and cyclic polyamines. Its long aliphatic chain with reactive bromine ends allows for ring-closing reactions, making it valuable in supramolecular chemistry. Also employed in the development of specialty surfactants and phase-transfer catalysts. Additionally, it serves as a building block in polymer chemistry for creating cross-linked networks and functionalized polymers with tailored chain lengths.
