Chloral hydrate, also known as trichloroacetaldehyde monohydrate, 2,2,2-trichloro-1,1-ethanediol, and under the tradenames Aquachloral, Novo-Chlorhydrate, Somnos, Noctec, and Somnote, is a sedative and hypnotic drug as well as a chemical reagent and precursor. Its chemical formula is C 2 H Cl 3 O .H 2 O. It is used for the short-term treatment of insomnia and as a sedative before minor medical or dental treatment. It has been largely displaced by the development of benzodiazepines. It was also formerly used as in veterinary medicine as a general anesthetic. Today, it is commonly used as an ingredient in the veterinary anesthetic Equithesin. In therapeutic doses for insomnia it is effective within sixty minutes, it is rapidly metabolized into trichloroethanol and trichloroacetic acid. Higher doses can depress respiration and blood pressure. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See for details.

A hypnotic and sedative used in the treatment of insomnia. The safety margin is too narrow for chloral hydrate to be used as a general anesthetic in humans, but it is commonly used for that purpose in animal experiments. It is no longer considered useful as an anti-anxiety medication. Source: National Library of Medicine, MeSH 2006
