Description

1-Chlorohexadecane is a high-purity, long-chain alkyl halide, also known as cetyl chloride. This compound serves as a versatile and critical alkylating agent and intermediate in organic synthesis, valued for its ability to introduce the hexadecyl (cetyl) group into target molecules. It is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to produce surfactants, phase-transfer catalysts, lubricant additives, and other functional materials.

Application

• Pharmaceutical Intermediate: Key starting material or alkylating agent in the synthesis of active pharmaceutical ingredients (APIs) and quaternary ammonium compounds.
• Surfactant & Detergent Manufacturing: Used to produce cationic surfactants like cetyltrimethylammonium chloride (CTAC), which are vital for personal care products, fabric softeners, and disinfectants.
• Phase-Transfer Catalyst (PTC) Synthesis: Acts as a precursor for quaternary ammonium salts that are effective catalysts in biphasic organic reactions.
• Agrochemical Production: Intermediate in the manufacture of certain pesticides, herbicides, and plant growth regulators requiring long-chain alkyl modifications.
• Lubricant & Fuel Additive: Used to synthesize additives that improve viscosity index, anti-wear properties, and corrosion inhibition.
• Organic Synthesis & Research: A valuable reagent in laboratories for nucleophilic substitution reactions, Grignard reagent preparation, and the construction of complex organic molecules.
• Polymer Modification: Employed to alkylate polymers or as a chain transfer agent to modify polymer properties.
