Description

1,3-Dioleoyl-2-Stearoylglycerol 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 behavior and metabolic properties. It serves as a high-value intermediate and functional ingredient for advanced research and product development in the pharmaceutical and nutraceutical 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: Acts as a structured lipid in specialized medical nutrition and dietary supplements designed for targeted metabolic effects.
• Biochemical Research: Serves as a standard or substrate in lipidomics research, enzymatic studies (e.g., lipase specificity), and metabolic pathway analysis.
• Cosmetic Ingredient: Employed in high-end skincare formulations for its emollient properties and ability to enhance the skin penetration of active compounds.
• Reference Standard: Utilized as an analytical standard in chromatography (HPLC, GC) for the identification and quantification of complex lipids.
• Food Science Research: Investigated for its functional properties in fat structuring and as a model for understanding fat digestion and absorption.

Quality Control

Our 1,3-Dioleoyl-2-Stearoylglycerol is manufactured under strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, fatty acid composition, and impurity profiles. Specifications can be aligned with research or cGMP requirements upon request.

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, as the compound is easily oxidized. For short-term use, store at 2-8°C. Allow the container to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake.
