Description

Linolenic Acid is a polyunsaturated ω-3 fatty acid essential for numerous biological and industrial processes. Its high degree of unsaturation makes it a valuable precursor for synthesizing specialized chemicals and a critical nutrient in advanced formulations. This compound is particularly significant for manufacturers in the nutraceutical, pharmaceutical, and specialty chemical sectors seeking high-purity bioactive ingredients or reactive intermediates.

Application

• Nutraceutical & Dietary Supplements: As a key ω-3 fatty acid (ALA - α-Linolenic Acid) for encapsulation in softgels, powders, and functional food fortification.
• Pharmaceutical Intermediates: Used in the synthesis of eicosanoids, lipid-based drug delivery systems, and active pharmaceutical ingredients (APIs) targeting inflammatory pathways.
• Biochemical Research: Serves as a standard, substrate, or culture medium component in lipidomics, cell signaling, and metabolic studies.
• Cosmetic & Personal Care: Incorporated into anti-aging and skin-barrier repair formulations for its moisturizing and skin-identical properties.
• Polymer & Resin Production: Acts as a renewable raw material for producing alkyd resins, drying oils, and bio-based polymers.
• Animal Feed & Aquaculture: An essential nutrient additive in high-performance feeds to promote healthy growth and development.

Quality Control

Our Linolenic Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, fatty acid profile, and peroxide value. Our quality commitment aligns with cGMP principles for pharmaceutical and nutraceutical applications, and we can support compliance with relevant standards including USP-NF and FCC upon request.

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 prolong shelf-life. Keep away from heat, sparks, and open flame. The container should be kept tightly sealed in a cool, dry, and well-ventilated place.
