Description

2-Chlorooctadecanoic Acid Methyl Ester is a high-purity, long-chain fatty acid derivative that serves as a versatile chemical intermediate. This compound is valued for its ability to introduce both chlorinated and ester functional groups into target molecules, enabling precise modifications in synthesis. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for applications ranging from polymer modification to the synthesis of complex organic molecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic chlorinated side chains.
• Agrochemical Synthesis: Serves as a key building block for manufacturing herbicides, pesticides, and plant growth regulators.
• Polymer & Plasticizer Production: Acts as a monomer or modifier in the creation of specialty polymers, resins, and plasticizers to alter flexibility and chemical resistance.
• Surfactant & Lubricant Additive: Employed in the formulation of industrial surfactants, corrosion inhibitors, and high-performance lubricant additives.
• Organic Synthesis Reagent: A valuable reagent in academic and industrial research laboratories for introducing the 2-chlorooctadecyl moiety into complex organic structures.
• Flavor & Fragrance Chemistry: Used as a precursor in the multi-step synthesis of specific aroma compounds and fragrance ingredients.
