Description

Methyl Arachidonate CAS NO 2566-89-4 is the methyl ester of arachidonic acid, a key long-chain polyunsaturated fatty acid (PUFA) of the ω-6 series. This high-purity derivative is essential for research and industrial applications requiring a stable, esterified form of arachidonic acid. It is primarily utilized by biochemical researchers, pharmaceutical developers, and manufacturers of specialized lipid standards and reference materials.

Application

• Biochemical Research: Critical as a substrate or standard in studies of eicosanoid biosynthesis, lipid metabolism, and cell signaling pathways.
• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of prostaglandins, leukotrienes, and other bioactive lipid mediators.
• Analytical Reference Standards: Used as a high-purity certified reference material (CRM) for gas chromatography (GC) and liquid chromatography (LC) analysis in food, clinical, and nutritional testing.
• Nutritional Science: Employed in the formulation and study of specialized lipid supplements and infant nutrition products.
• Cell Culture & In Vitro Studies: Provides a defined source of arachidonic acid for lipid supplementation in cell culture media.
