Description

Linolenic Acid Ethyl Ester is the ethyl ester derivative of the essential ω-3 fatty acid, α-linolenic acid (ALA). This high-purity esterified form offers enhanced stability and solubility, making it a versatile and valuable intermediate for advanced synthesis and formulation. It is a critical raw material for manufacturers in the nutraceutical, pharmaceutical, cosmetic, and specialty chemical industries, where precise fatty acid profiles are required.

Application

• Pharmaceutical & Nutraceutical Intermediates: Used in the synthesis of specialized lipid-based drug delivery systems (e.g., liposomes) and as a precursor for high-purity ω-3 concentrates and supplements.
• Biochemical Research & Standards: Serves as a pure analytical standard for chromatography (GC, HPLC) and in metabolic pathway studies related to essential fatty acids.
• Cosmetic & Personal Care Actives: Incorporated into advanced skincare formulations for its emollient properties and as a carrier for active ingredients, leveraging its good skin penetration.
• Specialty Polymer & Resin Modification: Acts as a reactive monomer or plasticizer in the production of bio-based polymers, coatings, and resins to modify flexibility and properties.
• Food-Grade Ingredient Synthesis: Employed as a building block for creating food additives, flavoring agents, and other lipid-based functional ingredients.
• Lubricant & Functional Fluid Additives: Used in the formulation of bio-lubricants and environmentally friendly industrial fluids due to its favorable lipid characteristics.

Quality Control

Our Linolenic Acid Ethyl Ester is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including GC/HPLC for purity and assay, peroxide value, and identity confirmation (IR, NMR), to ensure it meets stringent specifications for sensitive applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at 2-8°C to minimize oxidation and maintain stability. Keep away from heat, sparks, and open flame. The container should be kept tightly sealed in a cool, dry, and well-ventilated place.
