Description

1,2-Dipalmitoyl-3-Linoelaidoyl-Rac-Glycerol CAS NO 344791-14-6 is a structured triglyceride (TAG) featuring a specific fatty acid composition at the sn-1, sn-2, and sn-3 positions of the glycerol backbone. This precise molecular architecture makes it a valuable synthetic standard and a critical intermediate for advanced lipid research and formulation development. It is essential for scientists and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries who require high-purity, well-defined lipids for analytical calibration, metabolic studies, and the creation of sophisticated lipid-based delivery systems.

Application

• Analytical Reference Standard: Used as a high-purity calibrant in chromatographic techniques (HPLC, GC) for the quantification and characterization of complex lipid mixtures.
• Biochemical Research: Serves as a critical substrate or model compound in studies of lipid metabolism, enzyme specificity (e.g., lipases), and membrane biophysics.
• Pharmaceutical Excipient Development: Employed as a structured lipid component in the research and development of advanced drug delivery systems, such as lipid nanoparticles (LNPs) and self-emulsifying drug delivery systems (SEDDS).
• Nutraceutical Formulation: Acts as a specialized ingredient in the design of structured nutritional lipids with targeted absorption and metabolic properties.
• Cosmetic Science: Utilized in the formulation of high-end skincare products for its emollient properties and as a carrier for active ingredients.
• Synthetic Chemistry Intermediate: Provides a defined starting material for the chemical synthesis of more complex, labeled, or modified glycerolipids.

Quality Control

Our 1,2-Dipalmitoyl-3-Linoelaidoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment (HPLC, GC) and identity confirmation (MS, NMR), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request.

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., argon or nitrogen) to minimize oxidation. Allow the product to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake.
