In a beaker 33 g of chloral hydrate is dissolved in 40 ml of water with vigorous stirring then a solution is prepared from very cold water, 05 g of sodium hydroxide and 3 g of sodium borohydride, the chloral hydrate beaker is immersed in an ice water bath and slow addition of the borohydride is started. It is a two steps synthesis where first isonitrosoacetanilide is prepared from aniline, chloral hydrate, and hydroxylamine hydro-chloride finally cyclization of isonitrosoacetanilide under strong acid conditions eg polyphosphoric acid, yields 2,3-dioxoindoline.

Chloral hydrate is a starting point for the synthesis of other organic compounds it is the starting material for the production of chloral , which is produced by the distillation of a mixture of chloral hydrate and sulfuric acid , which serves as the desiccant. Although, in principle, chloral hydrate can easily be made from chloral by adding water, in practice chloral itself is made from chloral hydrate, by treatment with sulfuric acid chloral is not much use in its own right, but is a starting point in the manufacture of ddt and can also be used to produce chloroform, though this is usually done by.
Chloral hydrate and trichloroethanol are further oxidized, mainly in the smooth endoplasmic reticulum of the liver and kidney, to inactive trichloroacetic acid with a help of an aldehyde dehydrogenase, which is located in both liver and erythrocytes.

Chloral was the first hypnotic drug and is a precursor in the commercial synthesis of the insecticide ddt, which was introduced in 1941 chloral was an important chemical in the chloral hydrate is administered in the management of alcohol withdrawal symptoms, the usual dose is 500 mg–1 g repeated at 6-h intervals if needed generally. Chemical synthesis, perhaps especially of an organic compound, can almost always be accomplished with a wide variety of pathways maybe one of them is the best for some reason: cost of reactants, fewest steps, highest yield shortest time, easiest scale-up. Chloral hydrate () definition (nci) a synthetic monohydrate of chloral with sedative, hypnotic, and anticonvulsive properties chloral hydrate is converted to the active compound trichloroethanol by hepatic alcohol dehydrogenase.
