Description

8-Hydroxyoctadecanoic Acid Methyl Ester is a high-purity fatty acid methyl ester derivative, serving as a versatile intermediate and building block in advanced organic synthesis. Its value lies in the unique combination of a long aliphatic chain, a reactive hydroxyl group, and an ester functionality, enabling precise chemical modifications. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel surfactants, lubricant additives, or bioactive molecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex lipid-based drug molecules and prodrugs.
• Agrochemical Synthesis: Serves as a key precursor for creating specialized surfactants and adjuvants used in pesticide and herbicide formulations.
• Specialty Surfactants & Emulsifiers: The hydroxyl group allows for further functionalization to produce non-ionic surfactants with specific HLB values for industrial and cosmetic applications.
• Lubricant & Fuel Additive Precursor: Acts as a building block for synthesizing high-performance esters that improve lubricity and cold-flow properties.
• Polymer Modification: Employed to introduce long-chain alkyl groups into polymers, enhancing flexibility, hydrophobicity, or biocompatibility.
• Research & Development: A valuable standard and reagent in organic chemistry research for studying fatty acid metabolism and esterification reactions.
