Description

10,11-Dichloro-1-Undecanol is a versatile chlorinated fatty alcohol intermediate of significant industrial interest. This compound serves as a crucial building block for the synthesis of specialty surfactants, plasticizers, and high-performance polymers. It is particularly valuable for manufacturers in the agrochemical, pharmaceutical, and advanced materials sectors seeking to introduce specific chlorinated functionalities into their products.

Application

• Surfactant & Detergent Intermediate: Key precursor for synthesizing chlorinated non-ionic and cationic surfactants with enhanced stability and specific surface activity.
• Polymer & Resin Modification: Used as a reactive monomer or chain modifier to impart flame retardancy, hydrophobicity, and improved adhesion properties to polyesters, polyurethanes, and epoxy resins.
• Agrochemical Synthesis: Serves as an important intermediate in the production of specialized herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediate: Employed in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring a long-chain chlorinated alcohol moiety.
• Lubricant & Plasticizer Additive: Acts as a precursor for chlorinated derivatives that function as extreme pressure additives in lubricants and as secondary plasticizers.
• Corrosion Inhibitor Formulation: Used to develop film-forming corrosion inhibitors for metal treatment and protective coatings.
