Used primarily as an intermediate in organic synthesis, especially in the production of quaternary ammonium compounds which serve as biocides, disinfectants, and surfactants. It is also employed in the manufacture of specialty polymers and as a crosslinking agent in certain resin systems. Due to its long aliphatic chain, it imparts hydrophobic properties to final products, making it useful in coatings and water-repellent treatments. Additionally, it finds use in research settings for developing novel pharmaceuticals and agrochemicals where a spaced dihalide functionality is required.
