ChEBI: 3beta-Hydroxycholest-4-ene is a cholestanoid.

Purify 4,5-coprosten-3-ol by dissolving it in Et2O, adding an equal volume of MeOH and removing the Et2O with a stream of CO2 until crystallisation begins. The sterol crystallises in needles when cooled in an ice-salt bath. Dry it in vacuo. The acetate crystallises from aqueous MeOH m 85o.
