Methylpentynol (Methylparafynol, Dormison, Atemorin, Oblivon) is a tertiary hexanol with hypnotic/sedative and anticonvulsant effects. It was discovered by Bayer in 1913 and was used shortly thereafter for the treatment of insomnia, but its use was quickly phased out in response to newer drugs with far more favorable safety profiles.

The drug was marketed again in the United States, Europe and elsewhere from 1956 well into the 1960s as a rapid-acting sedative; it was overshadowed at that point by benzodiazepines and the continued popularity of non-barbiturate sedatives such as meprobamate.

Methylpentynol is prepared by reaction of butanone with sodium acetylide.
