| The dihydrate is a racemic mixture, a colorless monoclinic crystal with a relative density of 1.984. It is highly soluble in water and loses its crystalline water at 100°C to form an anhydrous compound. The hemihydrate has a relative density of 1.98 and a refractive index of 1.526 (β). It loses its crystalline water at 155°C and decomposes at 200–220°C. It is extremely soluble in water and slightly soluble in ethanol. | |||||||||
