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
