Description

cis-11,14,17-Eicosatrienoic Acid is a long-chain, polyunsaturated ω-3 fatty acid characterized by three cis-configured double bonds at the 11, 14, and 17 positions. This specific structural configuration makes it a valuable intermediate and reference standard in lipid biochemistry and nutritional research. It is primarily sought by researchers and manufacturers in the life sciences, pharmaceutical development, and nutraceutical sectors. The compound is essential for studying fatty acid metabolism, synthesizing specialized lipid mediators, and developing high-purity dietary supplements.

Application

• Biochemical Research: Used as a critical intermediate and reference standard in the study of fatty acid desaturation, elongation, and metabolism pathways.
• Pharmaceutical Development: Serves as a key starting material or intermediate for the synthesis of specialized pro-resolving mediators (SPMs) and other bioactive lipid compounds.
• Nutraceutical Formulation: Incorporated into high-purity dietary supplements and functional foods targeting ω-3 fatty acid supplementation.
• Analytical Standard: Employed as a certified reference material (CRM) for the accurate quantification and identification of fatty acids in complex matrices via GC, GC-MS, or HPLC.
• Cosmetic Science: Investigated for potential applications in advanced skincare formulations due to its role in skin lipid barrier function and anti-inflammatory properties.
• Cell Culture & In-Vitro Studies: Used to supplement media in biological studies to investigate the effects of specific ω-3 fatty acids on cell membrane fluidity and signaling.

Quality Control

Our cis-11,14,17-Eicosatrienoic Acid is produced and handled under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by FT-IR and NMR, purity assessment by GC or HPLC, and checks for related substances and residual solvents. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring traceability and compliance with your research or production specifications.

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 container to reach room temperature in a desiccator before opening to minimize moisture condensation. Keep away from strong oxidizers.
