Abstract:
Provided is a method for producing high-purity cholesterol which does not contain a substantial amount of desmosterol, said method comprising reacting cholesterol mixed with desmosterol with a halogenating reagent and water and then separating and removing the thus formed desmosterol derivative by crystallization.
