Description

5,8-Octadecadienoic Acid Methyl Ester is a high-purity fatty acid methyl ester (FAME) derivative, specifically the methyl ester of a conjugated diene fatty acid. This compound serves as a valuable chemical intermediate and reference standard for research and industrial synthesis. It is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and specialty chemical sectors for developing bioactive compounds and advanced materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prostaglandin analogs and other bioactive lipid molecules for drug development.
• Reference Standard: Serves as an analytical standard in gas chromatography (GC) and mass spectrometry (MS) for identifying and quantifying conjugated fatty acid derivatives.
• Nutraceutical Research: Investigated as a precursor or model compound for studying the metabolism and effects of conjugated linoleic acid (CLA) isomers.
• Organic Synthesis: Acts as a building block for producing surfactants, lubricant additives, and specialty polymers due to its reactive diene structure.
• Biochemical Studies: Utilized in lipidomics research to understand lipid pathways and membrane biochemistry.
