Description

12,15-Octadecadienoic Acid Methyl Ester is a high-purity fatty acid methyl ester (FAME) derivative, specifically the methyl ester of linoleic acid with conjugated double bonds at the 12 and 15 positions. This compound serves as a versatile chemical intermediate and reference standard for research and industrial synthesis. It is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and specialty chemical sectors requiring precise lipid components.

Application

• Pharmaceutical Intermediate: Used in the synthesis of bioactive lipid molecules, prostaglandins, and other specialized therapeutics.
• Biochemical Research: Serves as a critical reference standard and substrate in lipidomics, metabolic studies, and enzyme activity assays (e.g., lipoxygenase).
• Nutraceutical Formulation: A component in the development of conjugated linoleic acid (CLA) based dietary supplements and functional food ingredients.
• Organic Synthesis: Acts as a building block for producing surfactants, emulsifiers, and polymer precursors.
• Cosmetic Ingredient: Utilized in the formulation of skin-care products for its emollient properties.
• Analytical Standard: Employed as a high-purity calibrant in gas chromatography (GC) and mass spectrometry (MS) for accurate quantification of fatty acid profiles.
