Description

6,9-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 6 and 9 positions. This compound serves as a versatile and valuable intermediate in organic synthesis and industrial applications, prized for its specific chemical reactivity. It is primarily sought by manufacturers in the pharmaceutical, cosmetic, and specialty chemical sectors for use as a building block in synthesizing bioactive compounds, surfactants, and advanced polymer materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prostaglandins, leukotrienes, and other bioactive lipid mediators for research and drug development.
• Cosmetic & Personal Care Ingredient: Acts as an emollient or a key intermediate for producing specialty esters and derivatives used in skin care formulations.
• Chemical Synthesis Building Block: Serves as a precursor for producing conjugated linoleic acid (CLA) derivatives, surfactants, and lubricant additives.
• Research & Development: Employed in biochemical and nutritional studies as a standard or reagent for analyzing fatty acid metabolism.
• Polymer & Resin Modification: Utilized in the production of alkyd resins and polymers to modify flexibility and drying properties.
