ALLOBARBITAL Usage And Synthesis

Originator

Allobarbital, Fluorochem Ltd.

Uses

Allobarbital is a barbiturate derivative that is primarily used as an anticonvulsant. Allobarbital also shows hypnotic activity and is used to boost the activity of analgesic drugs. Studies show that Allobarbital is an effective promoters of hepatocarcinogenesis. Allobarbital is a Controlled Substance.

Definition

ChEBI: Allobarbital is a member of barbiturates.

Manufacturing Process

To a mixture of 43 parts barbituric acid, 200 parts of water and 5 parts of cuprous sulfate in 10 parts of water is added 82 parts of allylbromide. Then at room temperature is added 27 parts of sodium hydroxide (10% aqueous solution). 5,5-Diallylbarbituric acid is isolated by filtration. After recrystallization from water 5,5-diallylbarbituric acid has melting polint 169- 170°C.

Therapeutic Function

Sedative, Hypnotic
