Description

1,2-Dioleoyl-3-stearoyl-rac-glycerol is a structured triglyceride (TAG) composed of oleic and stearic fatty acids in a specific positional arrangement. This precise molecular architecture is critical for applications requiring controlled lipid behavior, such as in advanced lipid-based drug delivery systems and specialized nutritional formulations. It serves as a key intermediate and functional excipient for pharmaceutical, nutraceutical, and high-value chemical synthesis industries seeking reproducible and well-characterized lipid components.

Application

• Pharmaceutical Excipient: Used as a lipid matrix in the development of solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for enhanced drug solubility and targeted delivery.
• Nutraceutical Formulations: Serves as a structured lipid in specialized medical nutrition and high-performance dietary supplements designed for specific metabolic pathways.
• Biochemical Research: Acts as a standard or substrate in enzymatic studies (e.g., lipase activity assays) and metabolic research due to its defined structure.
• Cosmetic Ingredient: Employed in high-end skincare products as an emollient and carrier for active ingredients, providing stability and improved skin absorption.
• Chemical Synthesis: Functions as a versatile intermediate for the synthesis of more complex lipids, phospholipids, and other ester derivatives.
• Model Compound: Used in analytical chemistry as a reference standard for chromatographic methods (HPLC, GC) to identify and quantify triglycerides.
