Description

1,2-Distearoyl-Rac-Glycerol is a high-purity synthetic glyceride, specifically a diacylglycerol (DAG) with two stearic acid chains. This compound is a critical intermediate and functional ingredient valued for its role in lipid research, formulation science, and as a building block for more complex molecules. It is essential for manufacturers and R&D teams in the pharmaceutical, nutraceutical, and specialty chemical industries seeking reliable, high-quality lipid components for advanced applications.

Application

• Pharmaceutical Excipient: Used as a lipid component in the development of solid lipid nanoparticles (SLNs), liposomes, and other advanced drug delivery systems to enhance drug solubility and bioavailability.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies, particularly those involving lipases and phospholipases, and in metabolic pathway research.
• Nutraceutical Formulations: Employed as an emulsifier and structuring agent in functional food and dietary supplement products.
• Cosmetic Ingredient: Acts as an emollient and texture enhancer in high-end skincare creams and lotions.
• Chemical Synthesis: A key intermediate for the synthesis of more complex lipids, phospholipids (like phosphatidic acids), and prodrugs.
• Reference Standard: Used as an analytical standard in chromatography (HPLC, GC) for quality control and method development in laboratories.
