Description

1,2-Dieicosapentaenoyl-3-Palmitoyl-Rac-Glycerol CAS NO 115433-29-9 is a structured triacylglycerol (TAG) featuring a unique fatty acid composition, combining long-chain polyunsaturated eicosapentaenoyl (EPA) residues with a saturated palmitoyl moiety. This specific molecular architecture is of significant interest for advanced nutritional and pharmaceutical research, particularly in the formulation of specialized lipid-based delivery systems. It serves as a critical intermediate or reference standard for developers in the nutraceutical, cosmeceutical, and lipidomics sectors seeking to engineer functional lipids with targeted metabolic or structural properties.

Application

• Pharmaceutical Research & Development: As a key intermediate in the synthesis of structured lipids for drug delivery vehicles, enhancing bioavailability of lipophilic active pharmaceutical ingredients (APIs).
• Nutraceutical Formulation: Used in the development of high-value dietary supplements and medical nutrition products aimed at modulating lipid metabolism and providing essential fatty acids.
• Biochemical & Lipidomics Research: Serves as a critical reference standard or substrate in metabolic pathway studies, enzyme assays (e.g., lipase specificity), and analytical method development.
• Cosmeceutical Applications: Incorporated into advanced skincare formulations for its potential skin-barrier repairing and anti-inflammatory properties derived from its EPA content.
• Specialty Chemical Synthesis: Acts as a building block for the chemical or enzymatic synthesis of more complex, value-added glycerolipids and phospholipids.

Quality Control

Our 1,2-Dieicosapentaenoyl-3-Palmitoyl-Rac-Glycerol is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical characterization using techniques such as HPLC, GC, and NMR to ensure identity, purity, and fatty acid composition. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and compliance with your research or formulation requirements.

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 minimize oxidation. Allow the container to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake.
