Chemical compound

Bromal hydrate is an organobromine compound with the chemical formula C2H3Br3O2. It is the bromine analogue of chloral hydrate. Bromal hydrate forms when bromal is reacted with water. It decomposes to bromal and water upon distillation. It has hypnotic and analgesic properties but acts like a stimulant at lower doses. Bromal hydrate is more physiologically active than its chlorine analogue, chloral hydrate. Its direct effect on the heart muscles is stronger than that of chloral hydrate. Its analgesic effects were attributed to the proposed metabolism to bromoform.

It was also tried as a medication for epilepsy, but was found ineffective.
