Description

1,3-Dioleoyl-2-lauroyl-rac-glycerol is a structured triglyceride (TAG) with a specific fatty acid composition, where oleic acid (C18:1) occupies the sn-1 and sn-3 positions and lauric acid (C12:0) occupies the sn-2 position. This precise molecular architecture is critical for applications requiring controlled lipid digestion, absorption, and metabolic response. It serves as a high-value 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 bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Nutraceutical Formulation: A key component in structured lipid formulations designed for clinical nutrition, infant formula, and medical foods to mimic human milk fat or provide specific metabolic benefits.
• Biochemical Research: Serves as a critical standard and substrate in lipidomics research, enzymatic studies (e.g., lipase specificity), and metabolic pathway analysis.
• Reference Material: Employed as a high-purity certified reference material (CRM) for analytical method development and calibration in chromatography (HPLC, GC).
• Cosmetic Ingredient: Utilized in high-end skincare formulations as an emollient and carrier for active compounds, offering excellent skin compatibility.
• Chemical Synthesis Intermediate: Acts as a building block for the synthesis of more complex lipids, phospholipids, and other specialty esters.
