Description

(8Z,11Z,14Z)-Ethyl Octadeca-8,11,14,17-Tetraenoate is a high-purity ethyl ester of stearidonic acid, a key ω-3 fatty acid derivative. This compound is valued for its role as a versatile synthetic intermediate and a potential standard for analytical research in lipid chemistry. It is primarily sought by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and specialty chemical sectors for developing bioactive compounds and reference materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates targeting inflammatory pathways and metabolic disorders.
• Nutraceutical Research: Serves as a precursor or reference standard in the development of concentrated ω-3 supplements and functional food ingredients.
• Biochemical Research: Acts as a critical substrate or standard in lipidomics, enzymology studies, and metabolic pathway analysis.
• Specialty Chemical Synthesis: Employed as a building block for producing surfactants, lubricant additives, and other performance chemicals with specific fatty acid profiles.
• Analytical Standard: Provides a high-purity reference material for gas chromatography (GC) and high-performance liquid chromatography (HPLC) methods in quality control laboratories.
