Description

1,3-Distearoyl-2-Linoleoyl-Rac-Glycerol is a structured triglyceride (TAG) composed of two saturated stearic acid chains and one unsaturated linoleic acid chain. This specific fatty acid configuration is significant for its role as a key intermediate in lipid research and the synthesis of specialized lipid-based formulations. It is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors for developing drug delivery systems, reference standards, and functional lipids.

Application

• Pharmaceutical Research & Development: Used as a critical intermediate or model compound in the study of lipid metabolism, lipase activity, and the development of lipid-based drug delivery systems (e.g., solid lipid nanoparticles, liposomes).
• Reference Standard: Serves as a high-purity analytical standard for chromatography (HPLC, GC) to identify and quantify triglycerides in complex biological or food matrices.
• Nutraceutical & Specialty Lipid Synthesis: Acts as a building block for synthesizing structured lipids with tailored nutritional and physical properties for medical foods and dietary supplements.
• Biochemical Research: Employed in enzymatic studies to investigate substrate specificity of lipases and phospholipases.
• Cosmetic & Personal Care Formulations: Can be utilized as an emollient or texture-enhancing agent in high-end skincare products due to its specific lipid profile.
• Chemical Synthesis Intermediate: Provides a defined triglyceride backbone for further chemical modification, such as hydrogenation or transesterification, to create novel compounds.
