Description

1-Linoleoyl-2-Oleoyl-3-Stearoyl-Rac-Glycerol is a well-defined synthetic triacylglycerol (TAG) with a specific fatty acid composition at each glycerol position. This compound matters as a high-purity reference standard and a critical raw material for advanced lipid research and formulation development. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries who require precise, structurally-defined lipids for analytical calibration, metabolic studies, and the creation of sophisticated lipid-based delivery systems.

Application

• Analytical Reference Standard: Used as a primary standard in chromatography (HPLC, GC) for the identification and quantification of complex lipid mixtures in biological and food samples.
• Biomedical & Pharmaceutical Research: Serves as a model substrate for studying lipid metabolism, enzyme kinetics (e.g., lipases), and membrane biophysics.
• Lipid-Based Drug Delivery Systems: A key component in the development of advanced lipid nanoparticles (LNPs), solid lipid nanoparticles (SLNs), and self-emulsifying drug delivery systems (SEDDS) for enhanced drug solubility and bioavailability.
• Nutraceutical & Functional Food Development: Employed in the formulation of structured lipids designed for specific nutritional or therapeutic benefits.
• Cosmetic & Personal Care Formulations: Acts as an emollient and skin-conditioning agent in high-end skincare products, providing stability and specific texture properties.
• Biochemical Reagent: Utilized in enzymatic assays and as a substrate for the production of other specialized lipid derivatives.

Quality Control

Our 1-Linoleoyl-2-Oleoyl-3-Stearoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical characterization using techniques including HPLC, GC, and NMR to confirm identity, isomeric purity, and chemical purity. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. For short-term use, storage at 2-8°C is acceptable. Allow the product to reach room temperature in a desiccator before opening to prevent condensation and moisture absorption.
