Used primarily as a chemical intermediate in organic synthesis, particularly in the production of quaternary ammonium compounds and other specialty chemicals. It serves as an alkylating agent due to the reactive chloroethyl group, enabling the introduction of long-chain alkyl functionalities into molecules. Its lipophilic nature makes it suitable for applications in surfactants, lubricants, and emulsifiers in industrial formulations. Also explored in controlled release systems and polymer modification for enhanced compatibility and performance.
