Description

Stearidonic Acid CAS NO 111174-40-4 is a long-chain ω-3 fatty acid, specifically an 18-carbon polyunsaturated fatty acid with four double bonds. This compound serves as a critical biosynthetic intermediate in the production of longer-chain ω-3 fatty acids like eicosapentaenoic acid (EPA). It is essential for manufacturers in the nutraceutical, pharmaceutical, and advanced lipid research sectors seeking a high-purity, plant-sourced ω-3 precursor for product development and clinical studies.

Application

• Nutraceutical & Dietary Supplement Formulation: As a key ingredient in ω-3 supplements targeting anti-inflammatory and cardiovascular health benefits.
• Pharmaceutical Intermediate: For the synthesis of higher-value, long-chain ω-3 fatty acids such as EPA and docosahexaenoic acid (DHA) in drug development.
• Clinical & Nutritional Research: Used as a reference standard and active component in studies investigating the metabolism and health effects of ω-3 fatty acids.
• Functional Food & Beverage Fortification: Incorporated into foods and drinks to enhance their nutritional profile with a plant-based ω-3 source.
• Cosmeceutical Products: Utilized in skincare formulations for its potential anti-inflammatory and skin-barrier supporting properties.
• Biochemical Reagent: Serves as a substrate or standard in enzymatic assays and lipidomics research.

Quality Control

Our Stearidonic Acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling via techniques like HPLC and GC, to ensure it meets stringent specifications for research and production use. Certificates of Analysis (COA) documenting purity, identity, and safety parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below. This product is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
