paraldehyde

colourless liquid of disagreeable taste and pungent odour used in medicine as a sedative-hypnotic drug and in chemistry in the manufacture of organic chemicals. When administered as a medicine, it is largely excreted by the lungs and gives an unpleasant odour to the breath. It is most useful for recalcitrant cases and is an older drug for treatment of acute alcoholic dementia.
