Description

1-Hexadecanoyl-3-Octadecanoyl-Rac-Glycerol is a synthetic mixed triglyceride, specifically a racemic mixture of a glycerol molecule esterified with palmitic (hexadecanoic) and stearic (octadecanoic) acids at the 1 and 3 positions. This compound is valued for its role as a high-purity lipid standard and a versatile chemical intermediate in advanced research and specialty manufacturing. It is primarily needed by industries focused on lipidomics research, analytical chemistry, and the development of specialty surfactants, emulsifiers, and cosmetic/pharmaceutical formulations where defined fatty acid composition is critical.

Application

• Analytical Reference Standard: Used as a high-purity standard in gas chromatography (GC) and liquid chromatography (LC) for the identification and quantification of complex lipids in biological and food samples.
• Lipidomics and Biochemical Research: Serves as a critical substrate or model compound in studies of lipid metabolism, enzyme kinetics (e.g., lipase activity), and membrane biophysics.
• Specialty Chemical Synthesis: Acts as a key intermediate in the synthesis of more complex, structured lipids, phospholipids, and other ester-based compounds for specialized applications.
• Cosmetic and Pharmaceutical Formulations: Utilized as an emollient, texture enhancer, or carrier lipid in high-end skincare, creams, and topical drug delivery systems due to its specific fatty acid profile.
• Food Science Research: Employed in studies related to fat crystallization, nutritional science, and the development of functional food ingredients with tailored physical properties.
