Cholesterol n-Octanoate is widely used in the field of material science, particularly in the development of liquid crystal displays (LCDs). Its properties make it suitable for stabilizing liquid crystal phases, enhancing the performance and durability of display screens.

In the pharmaceutical industry, it serves as a key component in drug delivery systems. Its lipid-like structure allows it to be incorporated into liposomes and other nanocarriers, improving the solubility and bioavailability of poorly water-soluble drugs.

Additionally, it is utilized in cosmetic formulations, where it acts as an emollient and stabilizer, providing a smooth texture and enhancing the shelf life of skincare products. Its compatibility with various ingredients makes it a versatile additive in personal care items.

In research, Cholesterol n-Octanoate is often employed as a model compound to study lipid behavior, membrane interactions, and phase transitions, contributing to advancements in biochemistry and biophysics.
