Metabolite Identification
Common Name2,2,2-Trichloroethanol
Description2,2,2-Trichloroethanol, also known as CCL3ch2oh or trichloroethyl alcohol, belongs to the class of organic compounds known as chlorohydrins. These are alcohols substituted by a chlorine atom at a saturated carbon atom otherwise bearing only hydrogen or hydrocarbyl groups. It has, historically, been used as a sedative hypnotic. The hypnotic drug triclofos (2,2,2-trichloroethyl phosphate) is metabolized in vivo to 2,2,2-trichloroethanol. 2,2,2-Trichloroethanol is an extremely weak basic (essentially neutral) compound (based on its pKa). 2,2,2-Trichloroethanol exists in all living organisms, ranging from bacteria to humans. In humans, its pharmacological effects are similar to those of its prodrugs, chloral hydrate and chlorobutanol. Chronic exposure may result in kidney and liver damage.2,2,2-Trichloroethanol can be added to SDS-PAGE gels in order to enable fluorescent detection of proteins without a staining step. This imaging step is compatible with later analysis by, e.g., immunoblotting.2,2,2-trichloroethanol is an effective protecting group for carboxylic acids due to its ease in addition and removal. 2,2,2-Trichloroethanol is an organic compound related to ethanol, except the hydrogen atoms at position 2 are replaced with chlorine atoms.
