Potassium borohydride a chemical used in synthesis as a selective reducing agent. It is very selective and as such will only reduce ketones or aldehydes to their corresponding alcohols. It is used to synthesize chloramphenicol, vitamin A, thiopenicol, atropine, and scopolamine. It differs from other borohydrides as it is insoluble in ethanol, ether, and THF.
