Description

8Z,11Z,14Z,17Z-Eicosatetraenoic Acid is a high-purity, long-chain polyunsaturated fatty acid (PUFA) of significant biochemical interest. This compound serves as a critical intermediate and reference standard in the research and development of bioactive lipid mediators and nutritional supplements. It is essential for manufacturers and research institutions in the pharmaceutical, nutraceutical, and life science sectors requiring precise, high-quality fatty acid components for advanced formulations and analytical studies.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized pro-resolving mediators (SPMs) and other bioactive lipid compounds for anti-inflammatory research.
• Nutraceutical Research: Acts as a key ingredient or reference standard in the development of advanced ω-3 and ω-6 dietary supplements and functional foods.
• Biochemical Research: Serves as a critical substrate or standard in studies of fatty acid metabolism, desaturase enzyme activity, and eicosanoid biosynthesis pathways.
• Analytical Reference Standard: Provides a high-purity calibrant for Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) methods in quality control and research laboratories.
• Cell Culture & In Vitro Studies: Utilized in media formulations to study the effects of specific polyunsaturated fatty acids on cell signaling, membrane fluidity, and gene expression.
• Cosmeceutical Development: Incorporated into advanced skincare formulations targeting skin barrier function and inflammatory responses due to its role in lipid metabolism.

Quality Control

Our 8Z,11Z,14Z,17Z-Eicosatetraenoic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing all specifications, and our quality commitment aligns with cGMP principles for pharmaceutical intermediates and high-purity biochemicals.

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., nitrogen or argon) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture condensation. Keep away from strong oxidizers.
