Copper(II) chloride dihydrate (CAS 10125-13-0), with the chemical formula CuCl₂·2H₂O and a relative molecular mass of 170.5, is a blue-green orthorhombic crystal. It readily deliquesces in humid environments but easily effloresces in dry conditions. Additionally, it is soluble in water, alcohol, ammonia, and acetone, with moderate solubility in ether and ethyl acetate, making it a common catalyst for organic reactions, particularly in carbon-hydrogen activation processes. Its aqueous solution exhibits slight acidity. When heated to 100°C, it loses two water molecules of crystallization, but it is noteworthy that it tends to hydrolyze at high temperatures, making the production of anhydrous salt difficult. During the crystallization process from copper(II) chloride aqueous solution, the crystal form varies with temperature: the dihydrate is obtained between 26–42°C, the tetrahydrate below 15°C, while the trihydrate and monohydrate are formed at 15–25.7°C and above 42°C, respectively. Moreover, copper(II) chloride dihydrate has relatively low toxicity.
