Description

Eicosapentaenoic Acid Ethyl Ester is a highly purified ethyl ester derivative of the essential ω-3 fatty acid, eicosapentaenoic acid (EPA). This compound is a critical intermediate and active ingredient valued for its enhanced stability and bioavailability compared to the free acid form. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and advanced research sectors. The product is supplied under stringent quality controls to ensure it meets the exacting standards required for high-value applications.

Application

• Pharmaceutical Intermediates: A key starting material for the synthesis of prescription-grade ω-3 medications and lipid-regulating therapies.
• Dietary Supplement Formulation: Used as a concentrated, high-purity active ingredient in softgel capsules, liquid formulations, and other nutraceutical products targeting cardiovascular and cognitive health.
• Biomedical & Clinical Research: Employed in cell culture studies, metabolic pathway analysis, and as a standard in analytical method development for lipidomics.
• Functional Food & Beverage Fortification: Incorporated into specialized food products designed to deliver therapeutic levels of EPA, often requiring a stable ester form.
• Reference Standard: Serves as a high-purity certified reference material (CRM) for quality control laboratories and regulatory testing.
• Cosmeceutical Ingredients: Utilized in advanced skincare formulations for its anti-inflammatory properties and role in maintaining skin barrier function.

Quality Control

Our Eicosapentaenoic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling via HPLC, GC, and other validated methods. We provide full traceability and Certificates of Analysis (COA) are available for every shipment. Production can be aligned with relevant standards such as USP-NF or in-house pharmaceutical-grade specifications upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store unopened containers at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Once opened, use promptly and minimize exposure to air, heat, and moisture. Keep away from strong oxidizing agents.
