Description

Cholesteryl Octanoate (CAS No. 1182-42-9) is a high-purity cholesterol ester derived from the reaction of cholesterol with octanoic acid. This white to off-white crystalline powder is widely utilized in biochemical research, pharmaceutical formulations, and lipid metabolism studies due to its hydrophobic properties and structural similarity to natural lipid compounds. With a molecular formula of C₃₅H₆₀O₂, it serves as a critical standard in chromatographic analysis and as a model compound for investigating lipid bilayers and membrane dynamics. Our product is rigorously tested for purity (>98%) and stability, ensuring reliable performance in sensitive applications such as cell culture media supplementation and lipoprotein research. Packaged under inert gas to prevent oxidation, it is supplied in sealed amber vials with desiccant to maintain integrity.
