Description

Cholesteryl Acetate (CAS: 604-35-3) is a high-purity sterol ester derived from cholesterol, widely utilized in biochemical research, pharmaceutical development, and material sciences. With the molecular formula C₂₉H₄₈O₂, it features a cholest-5-en-3β-ol backbone acetylated at the 3-position, enhancing its lipophilicity and stability. This white crystalline solid (≥97% purity) is soluble in organic solvents like chloroform and ethanol but insoluble in water, making it ideal for lipid studies, membrane modeling, and as a precursor for steroid synthesis. Its role extends to LC/MS standards, reference materials, and investigations into cholesterol metabolism and lipid-protein interactions. Packaged under inert conditions to ensure longevity, our Cholesteryl Acetate meets stringent quality controls for reproducibility in sensitive applications.

Cholesteryl Acetate serves as a critical standard in chromatographic analysis of sterols and lipid profiling. Researchers employ it to study cholesterol esterification processes, particularly in atherosclerosis and metabolic disorder models. It also functions as a substrate for synthesizing modified sterols and liposomal formulations in drug delivery systems. In material science, it acts as a mesogen in liquid crystal development for display technologies.
