Description

Heneicosapentaenoic Acid Methyl Ester is a high-purity, long-chain ω-3 fatty acid methyl ester derivative. This compound serves as a critical reference standard and synthetic intermediate for research and development in advanced lipid chemistry. It is primarily utilized by pharmaceutical R&D, nutraceutical, and analytical chemistry laboratories for method development, biomarker studies, and the synthesis of specialized lipid-based compounds.

Application

• Pharmaceutical Reference Standard: Used for the identification, purity assessment, and quantification of ω-3 fatty acids and their metabolites in drug development and clinical research.
• Biochemical Research: Serves as a precursor or substrate in enzymatic studies, lipid metabolism research, and the investigation of eicosanoid pathways.
• Analytical Chemistry: Employed as an internal standard or calibrant in Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) for accurate lipid profiling.
• Nutraceutical R&D: Acts as a key intermediate in the development and analysis of high-purity ω-3 concentrates and specialized nutritional formulations.
• Organic Synthesis: Utilized as a building block for the synthesis of more complex lipid molecules, labeled compounds, or pharmaceutical actives.

Quality Control

Our Heneicosapentaenoic Acid Methyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and GC-MS, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting critical specifications. Our quality commitment supports applications requiring high-purity reference materials and intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. The material is easily oxidized and should be handled in a controlled environment. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
