Description

3-Hydroxyoctadecanoic Acid Methyl Ester is a high-purity fatty acid methyl ester derivative, serving as a critical chiral building block and intermediate in advanced organic synthesis. Its value lies in providing a defined, functionalized long-chain alkyl structure essential for constructing complex molecules with specific stereochemistry. This compound is particularly needed by research and development laboratories, pharmaceutical manufacturers, and specialty chemical producers working on lipid-based drug delivery systems, bioactive surfactants, and novel polymer precursors.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of sphingolipids, ceramides, and other bioactive lipid molecules.
• Biochemical Research: Standard or substrate in enzymatic studies involving lipases, esterases, and fatty acid metabolism pathways.
• Specialty Surfactant Synthesis: Precursor for manufacturing non-ionic surfactants and emulsifiers with tailored hydrophilic-lipophilic balance (HLB).
• Polymer Chemistry: Monomer or co-monomer for creating functional polymers and biodegradable materials with pendant hydroxyl groups.
• Lubricant & Fuel Additive Precursor: Intermediate in the production of high-performance ester-based lubricants and biodiesel additives.
• Cosmetic Ingredient Synthesis: Building block for emollients, wax esters, and skin-conditioning agents in personal care formulations.
