Description

1-o-Oleoyl-2-O,3-o-Distearoylglycerol is a structured triglyceride, a specific triacylglycerol molecule with defined fatty acid residues at the sn-1, sn-2, and sn-3 positions. This precise molecular architecture is critical for applications requiring controlled lipid behavior, bioavailability, and physical properties. It is a key intermediate and functional ingredient for advanced research and development in the pharmaceutical, nutraceutical, and specialty chemical industries.

Application

• Pharmaceutical Excipient: Used as a lipid matrix component in solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for drug delivery systems.
• Nutraceutical Formulations: Serves as a structured lipid in specialized nutritional products and fat-soluble vitamin delivery.
• Biochemical Research: Acts as a defined substrate or standard in enzymatic studies of lipases and lipid metabolism pathways.
• Cosmetic Ingredient: Employed in high-end skincare formulations for its emollient properties and skin barrier support.
• Reference Standard: Utilized as a high-purity analytical standard for chromatography (HPLC, GC) in quality control laboratories.
• Synthetic Intermediate: Provides a building block for the synthesis of more complex glycerolipids and phospholipid analogs.
