Choline chloride is an organic compound with the formula [(CH3)3NCH2CH2OH]+Cl−. It is a quaternary ammonium salt, consisting of choline cations ([(CH3)3NCH2CH2OH]+) and chloride anions (Cl−). It is a bifunctional compound, meaning, it contains both a quaternary ammonium functional group and a hydroxyl functional group. The anion of this salt, choline, occurs in nature in living beings.[2] Choline chloride is a white, water-soluble salt used mainly in animal feed.[3]
