Lithium hydroxide is an inorganic basic compound with a chemical formula LiOH. It is a white hygroscopic crystalline material that is soluble in water and slightly soluble in ethanol. It is largely used in organic synthesis to promote reaction due to its strong basicity. Lithium hydroxide is the only alkali hydroxide that does not show polymorphism, and its lattice possesses a tetragonal structure.
