Description

1-Stearoyl-2-Oleoyl-3-Linoleoyl-Rac-Glycerol is a well-defined, high-purity mixed triglyceride composed of stearic, oleic, and linoleic fatty acids. This specific triacylglycerol structure is valued for its reproducible composition and stability, making it an essential reference standard and functional ingredient. It is primarily utilized by research institutions, analytical laboratories, and manufacturers in the pharmaceutical, nutraceutical, and advanced lipid research sectors for method development, quality control, and product formulation.

Application

• Analytical Reference Standard: Used as a certified standard for the identification and quantification of complex lipids in HPLC, GC, and mass spectrometry analyses.
• Pharmaceutical Excipient & Carrier: Serves as a lipid-based carrier in advanced drug delivery systems, including lipid nanoparticles (LNPs) and self-emulsifying drug delivery systems (SEDDS).
• Biochemical Research: A critical substrate for studying lipase enzyme activity, lipid metabolism, and membrane biophysics in academic and industrial R&D.
• Nutraceutical Formulation: Employed as a structured lipid in specialized dietary supplements and medical nutrition products for its defined fatty acid profile.
• Cosmetic Ingredient: Acts as an emollient and skin-conditioning agent in high-end cosmetic and dermatological preparations.
• Food Science Research: Used as a model compound to investigate fat crystallization, oxidation stability, and texture properties in food product development.

Quality Control

Our 1-Stearoyl-2-Oleoyl-3-Linoleoyl-Rac-Glycerol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets the high standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical parameters such as assay, fatty acid composition, and impurity profiles.

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) to minimize oxidation. For long-term storage, keep the container sealed in a dry, cool environment. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation.
