Description

1,2-Dioleoyl-3-Stearoyl-Rac-Glycerol is a structured triglyceride, a triacylglycerol molecule with defined fatty acid residues at specific positions on the glycerol backbone. This precise molecular architecture is critical for applications requiring controlled lipid behavior, such as in advanced drug delivery systems and specialized nutritional formulations. It is an essential high-purity intermediate for pharmaceutical researchers, lipid chemists, and manufacturers in the nutraceutical and cosmetic industries seeking to engineer specific physical and metabolic properties.

Application

• Lipid Nanoparticle (LNP) Formulation: A key synthetic lipid component for constructing stable, biocompatible carriers for mRNA, siRNA, and other nucleic acid therapeutics.
• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, or bioavailability enhancer in advanced oral and topical drug formulations.
• Structured Lipid Research: Serves as a critical reference standard and building block in metabolic studies and the development of specialized nutritional lipids.
• Cosmetic & Dermal Delivery: Incorporated into high-end skincare products as an emollient and penetration enhancer for active ingredients.
• Biochemical Research: Utilized in membrane biophysics studies, enzyme substrate assays (e.g., for lipases), and cell culture media supplements.
• Synthetic Intermediate: Acts as a precursor for the synthesis of more complex phospholipids and other functionalized glycerolipids.

Quality Control

Our 1,2-Dioleoyl-3-Stearoyl-Rac-Glycerol is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical and research applications. A detailed Certificate of Analysis (COA) providing batch-specific data is supplied with every order.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below to minimize oxidation. Allow the sealed container to reach room temperature before opening to prevent moisture condensation. Store in a cool, dry, well-ventilated area away from incompatible materials.
