Description

1-Palmitoyl-2-Linoleoyl-3-Stearoyl-Rac-Glycerol is a high-purity, synthetic triacylglycerol (TAG) with a defined fatty acid composition at each sn-position of the glycerol backbone. This structured lipid is critical for research and development in advanced lipid science, offering a precise molecular standard for analytical calibration and metabolic studies. It serves as an essential raw material for pharmaceutical formulation scientists, nutraceutical developers, and biochemical researchers requiring well-characterized lipid molecules.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantification of complex lipids in drug products and biological matrices via techniques like LC-MS and GC.
• Biochemical Research: Serves as a substrate or model compound for studying lipase enzyme specificity, lipid metabolism pathways, and membrane biophysics.
• Nutraceutical Development: Acts as a key intermediate or active component in the formulation of structured lipids designed for specific nutritional and medical food applications.
• Cosmetic Science: Employed in high-end skincare formulations as an emollient and skin-identical lipid to enhance barrier function and product stability.
• Analytical Chemistry: Essential for calibrating analytical instruments and validating methods in lipidomics and food chemistry laboratories.
• Lipidomics: A crucial internal standard for the accurate identification and relative quantification of triacylglycerol species in complex samples.

Quality Control

Every batch of 1-Palmitoyl-2-Linoleoyl-3-Stearoyl-Rac-Glycerol is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and compositional accuracy. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment. We support compliance with cGMP and ISO 9001 standards for research and pharmaceutical applications.

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). Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation. Store away from strong oxidizers.
