Choline chloride is an organic compound with the formula (CH3)3NCH2CH2OH]Cl. It is bifunctional, containing both quaternary ammonium salt and an alcohol. The cation is choline, which occurs naturally. It is a white, water soluble salt used mainly in animal feed.
Choline chloride is mass-produced with world production estimated at 160 000 tons in 1999. Industrially, it is produce by the reaction of ethylene oxide, hydrogen chloride, and trimethylamine, or from the pre-formed salt:
It is also used as a clay control additive in fluids used for hydraulic fracturing.
