Description

cis-7,10,13,16,19-Docosapentaenoic Acid Methyl Ester is a high-purity methyl ester derivative of the ω-3 fatty acid docosapentaenoic acid (DPA, n-3). This compound serves as a critical intermediate and reference standard in the research and development of nutritional supplements, pharmaceuticals, and advanced lipid formulations. It is essential for scientists and manufacturers in the nutraceutical, pharmaceutical, and biochemical research sectors who require precisely characterized fatty acid derivatives for synthesis, analysis, and product development.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized lipid-based drug formulations and active pharmaceutical ingredients (APIs).
• Nutraceutical Research & Development: Acts as a key precursor or reference material in the development of advanced ω-3 dietary supplements and functional foods.
• Biochemical Research: Serves as a standard for analytical methods (GC, HPLC) and in studies investigating the biological functions and metabolism of ω-3 fatty acids.
• Lipidomics & Metabolomics: Employed as a critical analytical standard for the identification and quantification of complex lipid species in biological samples.
• Cosmetic & Personal Care Ingredients: Used in the formulation of high-end skincare products for its potential bioactive properties.
• Chemical Synthesis: Functions as a building block for the synthesis of more complex, structured lipids and conjugates.
