Description

5,8,11,14-Eicosatetraenoicacid(7Ci,8Ci,9Ci) is a high-purity, long-chain polyunsaturated fatty acid (PUFA) of significant research and industrial interest. This compound serves as a critical intermediate and reference standard in the synthesis of bioactive lipid mediators and specialized pro-resolving mediators (SPMs). It is essential for pharmaceutical R&D, analytical laboratories, and nutraceutical manufacturers focused on inflammation research, metabolic studies, and the development of high-value lipid-based products.

Application

• Pharmaceutical Research Intermediate: A key precursor in the chemical and enzymatic synthesis of eicosanoids, lipoxins, and other oxylipins for pharmacological studies.
• Biochemical Reference Standard: Used as an analytical standard in gas chromatography (GC) and high-performance liquid chromatography (HPLC) for the quantification of fatty acids in complex biological matrices.
• Nutraceutical Development: Employed in research for formulating advanced dietary supplements targeting metabolic and inflammatory pathways.
• Cell Culture & In Vitro Studies: Utilized in lipidomics research to study cell membrane fluidity, signaling pathways, and the biological effects of polyunsaturated fatty acids.
• Cosmeceutical Applications: Investigated for use in advanced skincare formulations aimed at modulating skin barrier function and inflammatory responses.
• Chemical Synthesis Building Block: Serves as a starting material for the organic synthesis of more complex, stereochemically defined lipid molecules.

Quality Control

Every batch of our 5,8,11,14-Eicosatetraenoicacid is produced and controlled under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from heat and incompatible materials.
