Description

1,2-Dioctadecanoyl-3-Hexadecanoyl-Rac-Glycerol is a synthetic, high-purity triacylglycerol (TAG) with a defined fatty acid composition, specifically featuring stearic (C18:0) and palmitic (C16:0) acid chains. This precise molecular structure makes it a critical standard and reference material for analytical chemistry and lipid research. It is essential for industries and laboratories requiring exact calibration, method development, and quality control of complex lipid mixtures.

Application

• Analytical Reference Standard: Primary use as a high-purity calibration standard for chromatographic techniques (HPLC, GC) and mass spectrometry in lipidomics.
• Biochemical Research: Used in studies of lipid metabolism, enzyme kinetics (e.g., lipase activity), and membrane biophysics due to its defined structure.
• Pharmaceutical Excipient Development: Serves as a model compound for formulating lipid-based drug delivery systems, such as solid lipid nanoparticles (SLNs) and self-emulsifying drug delivery systems (SEDDS).
• Food Science & Nutrition: Acts as a reference material for analyzing triglyceride profiles in fats, oils, and dairy products to ensure authenticity and quality.
• Cosmetic Ingredient Synthesis: Utilized as a controlled intermediate or benchmark for producing specialty esters and emollients with specific melting points and textures.
• Quality Control & Assurance: Employed by chemical suppliers and manufacturers to verify the purity and composition of commercial-grade mixed triglycerides.
