Description

Cholesteryl Linoleate is a high-purity cholesterol ester of the essential fatty acid linoleic acid. This compound is a critical biochemical intermediate and a valuable standard in lipid research and analytical chemistry. It serves as a key component for researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced materials sectors. Our supply of Cholesteryl Linoleate CAS NO 604-33-1 is characterized by exceptional purity and batch-to-batch consistency.

Application

• Biochemical Research & Standard: Used as a reference standard in chromatography (HPLC, GC) for the analysis of cholesterol esters, lipoproteins, and lipid profiles.
• Lipidomics & Metabolic Studies: A crucial reagent for studying lipid metabolism, membrane biophysics, and the role of specific cholesterol esters in cellular processes.
• Pharmaceutical Development: Employed in the formulation and testing of lipid-based drug delivery systems, such as liposomes and nanoemulsions.
• Nutraceutical & Cosmetic Ingredient: Acts as a bioactive component or an emollient in high-end skincare formulations and dietary supplement research.
• Material Science: Investigated for its self-assembly properties in the development of liquid crystals and advanced organic thin films.
• Diagnostic Kits: Utilized in the production of calibrators and controls for clinical diagnostic assays measuring cholesterol and related lipids.
