(2-BROMO-2-ETHYLBUTYRYL)UREA Usage And Synthesis

Chemical Properties

white crystalline powder

Originator

Antineuralgiae,Jelfa

Definition

ChEBI: Carbromal is a N-acylurea.

Manufacturing Process

120 parts urea and 258 parts 2-bromo-2-ethylbutyrylbromide was mixed and stood at room temperature for 12 hours; then the mixture was heated about 3 hours on water bath and adjusted to alkaline pH with sodium bicarbonate after cooling. The unreacted products was dissolved in brine, the insoluble part was filtered off. The recrystallization from ethanol gave the title product - (2-bromo-2-ethyl-butyryl)urea as the colorless, odorless crystals. MP 114°- 118°C.

brand name

Adalin (Sterling Winthrop).

Therapeutic Function

Hypnotic, Sedative

General Description

Odorless tasteless white crystalline powder. Saturated solution in water neutral to litmus.

Air & Water Reactions
