Metharbital was patented in 1905 by Emil Fischer working for Merck. It was marketed as Gemonil by Abbott Laboratories. It is a barbiturate anticonvulsant, used in the treatment of epilepsy. It has similar properties to phenobarbital.
Metharbital can be synthesized from 2,2-diethylmalonic acid and O-methylisourea.
