Description

13,16,19-Docosatrienoic Acid is a long-chain polyunsaturated fatty acid (PUFA) characterized by its three double bonds at the 13, 16, and 19 positions. This specific structural configuration makes it a valuable intermediate and reference standard in lipid biochemistry and nutritional research. It is primarily sought by professionals in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors for its role in metabolic studies and as a building block for specialized lipid compounds.

Application

• Biochemical Research: Used as a high-purity reference standard and intermediate in the study of fatty acid metabolism, desaturase enzyme activity, and lipidomics.
• Pharmaceutical Development: Serves as a key synthetic precursor or an analytical standard in the development of lipid-based drug formulations and active pharmaceutical ingredients (APIs).
• Nutraceutical & Cosmetic Ingredient: Investigated for potential applications in specialized dietary supplements and high-end cosmetic products targeting skin health and cellular function.
• Organic Synthesis: Acts as a versatile chiral building block for the synthesis of complex natural products, prostaglandin analogs, and other bioactive molecules.

Quality Control

Our 13,16,19-Docosatrienoic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and relevant industry standards for research and development materials.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture absorption.
