Description
Copper(II) Chloride Dihydrate Product Overview
Copper(II) chloride dihydrate (CuCl2·2H2O) forms blue-green crystals that dissolve very easily in water, alcohol and acetone. When heated, it loses its water of crystallization and turns into yellow-brown anhydrous CuCl2.
The chemical industry uses it as a catalyst component in the oxychlorination of Ethylene to make ethylene dichloride for PVC, and as a co-catalyst in the Wacker oxidation. Printed circuit board producers use cupric chloride solutions to etch copper. It also serves as a raw material for copper pigments and dyes and for other copper compounds.
Other applications include wood preservation, textile mordanting, electroplating and blue-green flame colors in pyrotechnics. For other copper salts, see Copper Sulfate and Copper(II) acetate 1-hydrate.

Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Frequently Asked Questions
What is the difference between the dihydrate and anhydrous form?
The dihydrate contains two water molecules and forms blue-green crystals. The anhydrous form is yellow-brown and is preferred where water must be avoided.
Is copper(II) chloride used for PCB etching?
Yes. Cupric chloride solutions are widely used to etch copper on printed circuit boards and can be regenerated.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
