Metharbital was patented in 1905 by Emil Fischer working for Merck.[2] It was marketed as Gemonil by Abbott Laboratories. It is a barbiturate anticonvulsant, used in the treatment of epilepsy.[3][4] It has similar properties to phenobarbital.

History[edit]

  • 1952 Gemonil was introduced by Abbott Laboratories.
  • 1990 Abbott stopped marketing.

Synthesis[edit]

Metharbital can be synthesized from 2,2-diethylmalonic acid and O-methylisourea.[5][6][2]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
