Chloral hydrate is a geminal diol with the formula Cl 3 C−CH(OH) 2. It was first used as a sedative and hypnotic in Germany in the 1870s. Over time it was replaced by safer and more effective alternatives but it remained in usage in the United States until at least the 1970s. [ 4 ]
Chloral tends to form adducts with water (to give chloral hydrate) and alcohols. Aside from its tendency to hydrate, chloral is notable as a building block in the synthesis of DDT. For this purpose, chloral is treated with chlorobenzene in the presence of a catalytic amount of sulfuric acid: Cl 3 CCHO + 2 C 6 H 5 Cl → Cl 3 CCH(C 6 H 4 Cl) 2 ...
Dichloralphenazone is a 1:2 mixture of antipyrine with chloral hydrate. In combination with paracetamol and isometheptene, it is the active ingredient of medications for migraine and tension headaches, including Epidrin and Midrin. Performance impairments are common with this drug and caution is advised, for example when driving motor vehicles.
Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
Chloral hydrate/magnesium sulfate/pentobarbital sodium, brand name Equithesin, is a combination anesthetic agent used as a general anesthetic in horses. [1] It is administered intravenously to effect. For many years, it was the most commonly used injectable anesthetic in horses.
Chloral hydrates to chloral hydrate in the body. Chloral hydrate is either reduced to 2,2,2-trichloroethanol or oxidised to trichloroacetic acid . Monochloroacetic acid , [ 38 ] dichloroacetic acid [ 39 ] and trichloromethane [ 38 ] [ 40 ] [ 41 ] were also detected as minor metabolites of TCE.
The compound is a preservative, sedative, hypnotic and weak local anesthetic similar in nature to chloral hydrate. It has antibacterial and antifungal properties. [1] Chlorobutanol is typically used at a concentration of 0.5% where it lends long term stability to multi-ingredient formulations.
Following a rupture in supply 2014–2015 [3] the product returned to French pharmacies in June 2016 with the same composition, minus chloral hydrate, now banned, and with the indication "mouthwash" («bain de bouche») removed. [4] Among the new uses of the reformulation is endorsement of the Synthol gel as an umbilical cord antiseptic. [5]
