Description

Methyl 3-Hydroxyoctadecanoate is a high-purity fatty acid methyl ester derivative, specifically a hydroxy-substituted C18 compound. This specialty ester is valued for its bifunctional nature, combining a long alkyl chain with both ester and hydroxyl groups, which makes it a versatile intermediate for fine chemical synthesis. It is primarily sought by research and development laboratories, pharmaceutical intermediates manufacturers, and producers of advanced lubricants, surfactants, and polymer modifiers.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of complex bioactive molecules and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a standard or substrate in lipid metabolism studies, enzyme assays, and metabolic pathway analysis.
• Specialty Surfactant & Emulsifier Precursor: The hydroxyl group allows for further functionalization to create non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) values.
• Lubricant & Fuel Additive Synthesis: Serves as a precursor for synthesizing ester-based lubricants with enhanced low-temperature performance and biodegradability.
• Polymer Modification: Acts as a monomer or co-monomer for introducing long-chain alkyl and polar hydroxyl functionalities into polymers to modify physical properties.
• Cosmetic & Personal Care Ingredients: Used in the manufacture of emollients and conditioning agents for skin and hair care formulations.
