Description

cis-11,14,17-Eicosatrienoic Acid Ethyl Ester is a high-purity, long-chain polyunsaturated fatty acid (PUFA) ethyl ester derivative. This compound serves as a critical precursor and reference standard in the synthesis and analysis of complex lipids and bioactive molecules. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors, where precise fatty acid profiles are required.

Application

• Pharmaceutical Intermediate: Used in the research and development of lipid-based drug formulations and prodrugs.
• Biochemical Research: Acts as a critical standard and substrate in studies of fatty acid metabolism, desaturase enzyme activity, and eicosanoid pathways.
• Nutraceutical Synthesis: A key building block for the synthesis of specialized, high-value ω-3 fatty acid concentrates and esters.
• Reference Material: Serves as an analytical standard for Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) in quality control laboratories.
• Cosmetic Ingredient Development: Utilized in the formulation of advanced skincare products targeting skin barrier function and lipid restoration.
• Organic Synthesis: Employed as a chiral synthon or a protected fatty acid moiety in complex organic and medicinal chemistry synthesis.
