Copper(II) chloride dihydrate(CAS: 13933-17-0)

Copper(II) chloride dihydrate is a blue crystalline solid with a molecular weight of 230.56 g/mol. It is slightly soluble in water and reacts with bases to form copper(II) hydroxide and evolve hydrogen chloride gas. It is also reactive with reducing agents and can form various copper complexes.

Copper(II) chloride dihydrate can be synthesized by reacting copper(II) sulfate with sodium chloride in an aqueous solution followed by crystallization. This process often uses hydrochloric acid to precipitate copper(II) chloride dihydrate, resulting in a high yield and good selectivity.

Copper(II) chloride dihydrate is widely used in the pharmaceutical industry for the synthesis of copper-based chelating agents and in the polymer industry as a catalyst for certain polymerization reactions. It is also utilized in the production of sensors and semiconductors due to its properties.

When handling Copper(II) chloride dihydrate, use personal protective equipment such as gloves and safety glasses. Store it in a cool, dry place away from direct sunlight. If a spill occurs, ensure proper ventilation and dispose of it according to the safety data sheet (SDS) guidelines. This compound is corrosive and may release toxic fumes when heated or exposed to moisture.
