Description

Eicosapentaenoic Acid CAS NO 1553-41-9 is a long-chain ω-3 polyunsaturated fatty acid (PUFA) of significant commercial and nutritional importance. Its primary value lies in its potent anti-inflammatory properties and critical role in human health, making it a sought-after ingredient for high-value formulations. This essential fatty acid is in high demand from manufacturers in the pharmaceutical, nutraceutical, and advanced food supplement industries seeking to develop evidence-based health products.

Application

• Pharmaceutical Intermediates: A key active pharmaceutical ingredient (API) and precursor in the synthesis of specialized pro-resolving mediators (SPMs) and other lipid-based therapeutics.
• Dietary Supplements & Nutraceuticals: Formulated into high-purity softgel capsules, liquid oils, and emulsified concentrates to support cardiovascular, cognitive, and joint health.
• Clinical Nutrition & Medical Foods: Incorporated into enteral and parenteral nutrition formulas for patients with specific metabolic or inflammatory conditions.
• Infant Formula Fortification: Used to enrich formula milk, mimicking the fatty acid profile of human breast milk to support neurological development.
• Functional Food & Beverage Enrichment: Added to foods, dairy products, and beverages to create heart-healthy and anti-inflammatory consumer products.
• Cosmeceutical & Topical Formulations: Utilized in advanced skincare products for its anti-inflammatory and skin-barrier repairing benefits.
• Research & Biochemical Reagents: Serves as a high-purity standard and reagent in lipidomics research, cell culture studies, and biochemical assays.
