Description

cis-11,14,17-Eicosatrienoic Acid is a long-chain, polyunsaturated ω-3 fatty acid characterized by its specific cis-configuration at the 11, 14, and 17 positions. This precise molecular structure makes it a valuable intermediate and reference standard for research in lipid biochemistry and metabolic pathways. It is primarily sought by professionals in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors. The compound serves as a critical building block for studying fatty acid metabolism and developing specialized lipid-based products.

Application

• Biochemical Research: Used as a high-purity reference standard and intermediate in the study of ω-3 fatty acid metabolism, desaturation, and elongation processes.
• Pharmaceutical Development: Serves as a key starting material or intermediate for the synthesis of specialized pro-resolving mediators (SPMs) and other bioactive lipid molecules.
• Nutraceutical R&D: Employed in research for developing advanced nutritional supplements targeting specific metabolic and inflammatory pathways.
• Analytical Chemistry: Utilized as an analytical standard in gas chromatography (GC) and high-performance liquid chromatography (HPLC) for the quantification and qualification of fatty acid profiles.
• Cosmetic Science: Investigated for potential applications in advanced skincare formulations due to its structural role in skin lipid barriers.
• Organic Synthesis: Acts as a chiral synthon for the construction of complex natural products and novel organic compounds with targeted biological activity.

Quality Control

Our cis-11,14,17-Eicosatrienoic Acid is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC and GC analysis, to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality systems are designed to support research and development applications where traceability and reliability are paramount.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below to minimize oxidation and ensure long-term stability. Allow the container to reach room temperature in a desiccator before opening to prevent moisture condensation. Keep away from oxidizers and strong acids.
