Description
Copper(I) Chloride Product Overview
Copper(I) chloride (CuCl) is a white to off-white crystalline powder that is almost insoluble in water but dissolves in hydrochloric acid and ammonia solutions. In moist air, it slowly oxidizes and turns green, so it needs dry, sealed storage.
In addition, chemists use it as a catalyst in Sandmeyer reactions, Ullmann-type couplings and oxidative couplings, and in the production of some chlorinated and nitrogen-containing intermediates. Similarly, gas treatment processes use copper(I) chloride solutions to absorb carbon monoxide, and pyrotechnics producers use it for blue flame colors. It also serves as a raw material for other copper compounds.
Furthermore, related copper compounds in our range include Copper(I) iodide, Copper(II) chloride 2-hydrate and Copper oxychloride.

⚠️ Safety & Handling: Harmful if swallowed, causes skin and eye irritation, and is very toxic to aquatic life. Avoid dust formation and release to the environment, and also wear gloves and eye protection. Store in tightly closed containers under dry conditions, because moist air oxidizes it. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
Why does copper(I) chloride turn green?
Because moist air oxidizes it to copper(II) compounds, it slowly turns green; sealed, dry storage prevents this.
What is copper(I) chloride used for in synthesis?
Mainly as a catalyst in Sandmeyer reactions as well as in copper-catalyzed coupling reactions.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
