Description

1-Hexadecanoyl-2-(trans-9-Octadecenoyl)-3-(cis-9,12-Octadecadienoyl)-Rac-Glycerol is a complex, structured triacylglycerol (TAG) featuring a specific arrangement of saturated, monounsaturated, and polyunsaturated fatty acid chains. This precise molecular architecture makes it a valuable high-purity reference standard and a critical intermediate for advanced lipid research and specialty chemical synthesis. It is primarily needed by pharmaceutical R&D laboratories, analytical chemistry suppliers, and manufacturers of high-value lipid-based products where defined molecular composition is paramount.

Application

• Analytical Reference Standard: Used as a high-purity calibrant in chromatographic methods (HPLC, GC) for the identification and quantification of complex lipids in biological and synthetic samples.
• Biochemical Research: Serves as a substrate or model compound in studies of lipid metabolism, enzyme kinetics (e.g., lipase specificity), and membrane biophysics.
• Pharmaceutical Development: Acts as a key intermediate or building block in the synthesis of specialized lipid drug conjugates, prodrugs, and advanced drug delivery systems like lipid nanoparticles (LNPs).
• Nutraceutical & Cosmeceutical R&D: Employed in the formulation and testing of structured lipids designed for targeted nutritional benefits or enhanced skin delivery in cosmetic actives.
• Synthetic Chemistry Intermediate: Provides a defined starting material for the chemical modification of glycerol backbones or specific fatty acid chains to create novel surfactants or functional lipids.
• Quality Control & Method Development: Essential for developing and validating analytical methods in quality control laboratories within the food, supplement, and chemical industries.

Quality Control

Every batch of 1-Hexadecanoyl-2-(trans-9-Octadecenoyl)-3-(cis-9,12-Octadecadienoyl)-Rac-Glycerol is produced and controlled under a strict quality management system. Our products undergo rigorous quality testing using advanced analytical techniques (including HPLC, GC, NMR) to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment, ensuring full traceability and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep 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 moisture condensation. Store away from strong oxidizers and heat sources.
