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]
