Used as an intermediate in organic synthesis, particularly in the production of specialty chemicals and polymers. It serves in the preparation of macrocyclic compounds and ligands for metal coordination chemistry. Due to its bifunctional chloro groups separated by a long aliphatic chain, it is employed in cross-linking reactions and the synthesis of crown ether analogs. Also utilized in the development of surfactants, agrochemicals, and pharmaceuticals where a nine-carbon spacer with terminal reactivity is required.
