Description

cis-5,8,11,14,17-Eicosapentaenoic Acid Methyl Ester is the methyl ester derivative of the essential ω-3 fatty acid eicosapentaenoic acid (EPA). This high-purity chemical intermediate is critical for research and the synthesis of bioactive compounds, offering a stable and defined form for precise formulation work. It is primarily utilized by the pharmaceutical, nutraceutical, and advanced research sectors for developing cardiovascular, anti-inflammatory, and neurological health products.

Application

• Pharmaceutical Intermediate: A key starting material for the synthesis of prescription-grade ω-3 concentrates and specialized lipid-based drug formulations.
• Nutraceutical Standard & Ingredient: Used as a reference standard for quality control and as a concentrated ingredient in high-potency dietary supplements.
• Biochemical Research: Essential for in-vitro and in-vivo studies investigating lipid metabolism, cell membrane fluidity, and eicosanoid signaling pathways.
• Cosmeceutical Actives: Incorporated into advanced skincare formulations for its anti-inflammatory and skin-barrier supporting properties.
• Analytical Chemistry: Serves as a critical standard in gas chromatography (GC) and mass spectrometry (MS) for the quantification of ω-3 fatty acids in complex matrices.
• Lipidomics: A vital component in lipid libraries for the identification and profiling of complex lipid species in biological samples.

Quality Control

Our cis-5,8,11,14,17-Eicosapentaenoic Acid Methyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC and HPLC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting compliance with research and cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at -20°C or below for long-term stability. For short-term use, store at 2-8°C. The material is easily oxidized and light-sensitive; minimize exposure to air and ambient light during handling.
