Description

1,2-Distearoyl-3-Linoleoyl-Rac-Glycerol is a structured triacylglycerol (TAG) composed of two saturated stearic acid chains and one unsaturated linoleic acid chain. This specific fatty acid configuration is critical for applications requiring a defined lipid matrix with controlled melting behavior and oxidative stability. It serves as a valuable synthetic intermediate and functional component for research and industrial formulation. Key industries that utilize this compound include pharmaceutical development, advanced lipid research, and specialty chemical manufacturing.

Application

• Pharmaceutical Excipient & Drug Delivery: Used as a lipid matrix component in solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for controlled drug release.
• Biochemical Research Standard: Serves as a reference compound and substrate in enzymatic studies of lipases and lipid metabolism pathways.
• Synthetic Lipid Intermediate: Acts as a key building block for the synthesis of more complex, structured phospholipids and glycoglycerolipids.
• Nutraceutical & Food Science: Investigated for use in structured lipids designed to have specific nutritional and metabolic properties.
• Cosmetic Formulations: Employed as an emollient and texture-enhancing agent in high-end skincare products.
• Material Science: Used in the development of bio-based polymers and surfactants with tailored hydrophobic properties.

Quality Control

Our 1,2-Distearoyl-3-Linoleoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and support our products with a detailed Certificate of Analysis (COA) upon request, which includes data from techniques such as HPLC, GC, and NMR to verify specification compliance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation. For long-term storage, keep the material in a cool, dry place, ideally at -20°C. Allow the container to reach room temperature before opening to prevent condensation and moisture ingress.
