Description

Cholesteryl Formate CAS NO 4351-55-7 is a cholesterol derivative where the 3β-hydroxyl group is esterified with formic acid. This chemical intermediate is significant for its role in synthesizing more complex steroidal compounds and modifying lipid properties. It is primarily required by research institutions and pharmaceutical companies engaged in lipid chemistry, material science, and the development of advanced drug delivery systems.

Application

• Key intermediate in the synthesis of other cholesteryl esters and modified sterols for research.
• Used in material science research for developing liquid crystals and organic thin films.
• Component in biomimetic membrane studies to investigate lipid bilayer properties and dynamics.
• Potential precursor for pharmaceutical excipients and advanced drug delivery vehicles like liposomes.
• Reference standard in analytical chemistry for chromatography (HPLC, GC) and spectroscopy.
• Used in cosmetic research for exploring novel lipid-based formulations.
