Description

Cholesteryl iso-Butyrate is a high-purity cholesterol derivative where the iso-butyric acid moiety is esterified to the 3β-hydroxyl group of the cholesterol backbone. This specific esterification is significant for modifying the physical and chemical properties of cholesterol, making it a valuable intermediate in advanced material synthesis and life science research. It is primarily sought after by R&D and production teams in the pharmaceutical, cosmetic, and specialty chemical industries for developing novel formulations and functional materials.

Application

• Pharmaceutical Intermediate: Used in the research and synthesis of novel drug candidates, particularly those targeting lipid metabolism or requiring cholesterol-based carriers.
• Lipid Research Standard: Serves as a reference standard or a model compound in biochemical and biophysical studies of membrane lipids and sterol esters.
• Cosmetic Ingredient: Employed in the formulation of high-end skincare products for its emollient properties and potential skin barrier enhancement.
• Liquid Crystal Material: Acts as a component in the development of chiral dopants or mixtures for liquid crystal displays (LCDs) and optical devices.
• Biomimetic Material Synthesis: Utilized to create synthetic lipids and vesicles that mimic natural cell membranes for drug delivery systems.
• Chemical Synthesis Building Block: Provides a functionalized cholesterol scaffold for further chemical modifications in organic synthesis.
