Copper chloride is an inorganic compound with the chemical formula CuCl2. This light brown solid slowly absorbs moisture to form a blue-green dihydrate. It occurs naturally as the anhydrous mineral tolbachite and dehydrated eriochalcite, and it also can be obtained industrially from the reaction of copper(II) oxide with hydrochloric acid, HCl: CuO + 2HCl – CuCl2 + H2O. The anhydrous form of copper(II) chloride is a yellow to brown, monoclinic solid, and the dihydrate has greenish blue orthorhombic crystals. Copper(II) chloride solutions are moderate to highly concentrated liquids, and they can be used in many different applications, including petrochemical cracking and automotive catalysts; water treatment and plating; textile dyeing and printing mordants; glass and ceramic pigments; and laundry-marking and invisible inks.

Copper(II) chloride is a strong oxidizing agent and is corrosive to aluminium. It is also toxic to humans and animals. It can irritate the skin and cause damage to the eyes. Inhaling it can cause coughing and lung irritation. It can also be absorbed through the gastrointestinal tract. Exposure to copper(II) chloride solutions can lead to severe skin burns, so it is important to use proper safety precautions when handling it.

Copper Chloride solutions are available in a variety of packaging options, from 55 gallon drums to smaller units and liquid totes. These solutions are commonly used in petrochemical cracking and automotive catalysts; in water treatment, plating and textile applications; and in optic, laser and crystal research.
