Description

1,2-Dielaidoyl-3-Stearoyl-Rac-Glycerol is a chemically defined triacylglycerol (TAG) with a specific fatty acid composition at each glycerol backbone position. This compound is a critical reference standard and a valuable synthetic intermediate for lipid research and specialty chemical synthesis. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced materials sectors who require high-purity, structurally defined lipids for analytical calibration, metabolic studies, and the development of lipid-based delivery systems.

Application

• Analytical Reference Standard: Used as a high-purity calibrant in chromatographic methods (HPLC, GC) for the identification and quantification of complex lipid mixtures.
• Biochemical Research: Serves as a substrate or model compound in studies of lipid metabolism, enzyme kinetics (e.g., lipase activity), and membrane biophysics.
• Pharmaceutical Development: Acts as a key synthetic intermediate or excipient in the formulation of lipid nanoparticles (LNPs) and other advanced drug delivery vehicles.
• Nutritional Science: Employed in metabolic studies to investigate the absorption and effects of specific dietary triglyceride structures.
• Specialty Chemical Synthesis: Used as a building block for the synthesis of more complex, structured lipids with tailored functional properties.
• Quality Control: Essential for the internal QC and method validation in laboratories analyzing fats, oils, and lipid-based products.

Quality Control

Our high-purity 1,2-Dielaidoyl-3-Stearoyl-Rac-Glycerol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets exacting standards for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. Allow the product to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake.
