. 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.[1] It has hypnotic and analgesic properties but acts like a stimulant at lower doses.[3] Bromal hydrate is more physiologically active than its chlorine analogue, chloral hydrate.[4] Its direct effect on the heart muscles is stronger than that of chloral hydrate.[3] Its analgesic effects were attributed to the proposed metabolism to bromoform.[5]

It was also tried as a medication for epilepsy, but was found ineffective.[1]
