Description

1,2-Dipalmitoyl-3-Linoleoyl-Rac-Glycerol is a structured triglyceride (TAG) with 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 reference standard and a key intermediate for research and development in lipid science. It is primarily utilized by scientists and manufacturers in the pharmaceutical, nutraceutical, and advanced food ingredient sectors who require well-defined lipid molecules for analytical calibration, metabolic studies, and the synthesis of complex lipid-based delivery systems.

Application

• Biochemical & Pharmaceutical Research: Serves as a critical reference standard for the analysis of complex lipids via techniques like HPLC and mass spectrometry.
• Lipidomics Studies: Used as a calibrant or internal standard to quantify triglycerides and understand lipid metabolism in biological systems.
• Drug Delivery System Development: Acts as a building block or model compound in the design of lipid nanoparticles (LNPs), liposomes, and other colloidal carriers for active pharmaceutical ingredients.
• Nutraceutical Formulation: Employed in research for developing structured lipids with targeted nutritional and health benefits.
• Synthetic Chemistry Intermediate: Provides a defined starting material for the chemical or enzymatic synthesis of more complex or labeled glycerolipids.
• Academic & Industrial R&D: Essential for universities and corporate R&D labs focusing on fat digestion, absorption, and the functional role of specific triglyceride regioisomers.

Quality Control

Our 1,2-Dipalmitoyl-3-Linoleoyl-Rac-Glycerol is produced and handled under strict quality management protocols to ensure identity, purity, and consistency. Each batch is characterized using advanced analytical techniques, including HPLC and NMR, to confirm its structural integrity and fatty acid profile. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity limits is provided with every shipment to support your research and compliance needs.

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 sealed container to reach room temperature before opening to prevent condensation and moisture ingress.
