Web1 jan. 2014 · Cocrystals can be divided into: cocrystal anhydrates, cocrystal hydrates (solvates), cocrystals of salts (unsolvated, unhydrated or solvated, hydrated). The … The first reported cocrystal, quinhydrone, was studied by Friedrich Wöhler in 1844. Quinhydrone is a cocrystal of quinone and hydroquinone (known archaically as quinol). He found that this material was made up of a 1:1 molar combination of the components. Quinhydrone was analyzed by numerous groups over the next decade and several related cocrystals were made from halogenated quinones.
