Choline hydroxide is a quaternary ammonium hydroxide with the chemical formula C5H15NO2, typically supplied as a 45% aqueous or methanolic solution. It is a strong organic base, colorless to slightly yellow, with a characteristic amine-like odor. The compound is manufactured through the reaction of choline chloride with potassium hydroxide or via ion exchange, followed by concentration to the desired strength.
In the pharmaceutical and chemical industries, choline hydroxide serves as a versatile intermediate and reagent. It is used in the synthesis of choline salts, such as choline bitartrate and choline citrate, and as a phase-transfer catalyst in organic reactions. Its high alkalinity and solubility make it valuable in various applications, from electronics to agrochemicals.
