Description

1-o-Palmitoyl-2-O,3-o-Distearoylglycerol is a well-defined, high-purity structured triglyceride. This compound is valued for its specific fatty acid composition and positional distribution, which provides consistent physical and chemical properties for advanced formulation work. It serves as a critical intermediate and functional ingredient for researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical sectors requiring precise lipid matrices.

Application

• Pharmaceutical Excipient: Used as a matrix former or carrier in lipid-based drug delivery systems (e.g., solid lipid nanoparticles, self-emulsifying drug delivery systems - SEDDS) to enhance bioavailability.
• Nutraceutical Ingredient: Acts as a structured lipid in specialized nutritional formulations and fat-soluble vitamin delivery.
• Biochemical Research: Serves as a standard or substrate in lipid metabolism studies, enzymatic assays, and membrane biophysics research.
• Cosmetic Formulations: Employed as an emollient and texture enhancer in high-end skincare products.
• Reference Standard: Used as an analytical standard in chromatography (HPLC, GC) for quality control of complex lipid mixtures.
• Specialty Chemical Synthesis: Functions as a key intermediate for the synthesis of more complex glycerides, phospholipids, or other ester derivatives.
