Description

Arachidonic Acid Ethyl Ester is a high-purity ethyl ester derivative of the essential ω-6 fatty acid, arachidonic acid. This compound serves as a critical intermediate and reference standard in advanced biochemical research and pharmaceutical development. It is primarily utilized by researchers and manufacturers in the nutraceutical, pharmaceutical, and life science sectors for studying lipid metabolism, inflammation pathways, and as a precursor for specialized lipid formulations.

Application

• Biochemical Research & Reference Standard: Used as a pure standard in chromatography (HPLC, GC) and mass spectrometry for quantifying arachidonic acid and its metabolites in biological samples.
• Pharmaceutical Intermediate: Serves as a key synthetic building block for the development of eicosanoid-based drugs and specialized lipid prodrugs.
• Nutraceutical Formulations: Incorporated into advanced lipid-based supplements targeting specific metabolic and inflammatory pathways.
• Cell Culture & In Vitro Studies: Applied in cell biology research to modulate eicosanoid production and study signal transduction mechanisms related to inflammation and immunity.
• Lipidomics & Metabolomics: An essential component in lipidomic profiling kits and studies aimed at understanding lipid roles in health and disease.
• Cosmeceutical Actives: Used in the development of high-end skincare products targeting skin barrier function and inflammatory skin conditions.

Quality Control

Our Arachidonic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by IR and NMR, purity assessment by GC/HPLC, and impurity profiling to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) detailing all test results are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures of -20°C or below. The product is easily oxidized and should be handled in a controlled environment to minimize exposure to air. Keep the container tightly sealed in a dry, cool, and well-ventilated place.
