Description

1,3-Dioleoyl-2-octanoyl-rac-glycerol is a structured triglyceride (TAG) with a specific fatty acid configuration at the sn-1, sn-2, and sn-3 positions of the glycerol backbone. This precise molecular architecture is critical for applications requiring controlled lipid digestion, absorption, and metabolic response. It serves as a high-value synthetic lipid intermediate and reference standard for research and development in the pharmaceutical, nutraceutical, and specialty chemical industries.

Application

• Pharmaceutical Excipient: Used in lipid-based drug delivery systems (LBDDS) to enhance the solubility and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Nutraceutical & Medical Nutrition: A key component in structured lipid formulations for specialized medical foods and dietary supplements, designed to provide targeted nutritional benefits.
• Biochemical Research: Serves as a critical reference standard and substrate in lipid metabolism studies, enzyme assays (e.g., lipase activity), and analytical method development.
• Cosmetic & Personal Care: Employed as an emollient and conditioning agent in high-end skincare formulations for its unique lipid properties.
• Chemical Synthesis: Acts as a versatile building block for the synthesis of more complex lipids, phospholipids, and other ester derivatives.
