Copper(II) chloride naturally occurs as the rare mineral eriochalcite, forming azure crystals. Unlike many copper salts, it exhibits amphoteric behavior, reacting with both acids and bases. In solution, it displays a chameleon-like color shift: blue when hydrated, green when concentrated, due to complex equilibria between [Cu(H₂O)₆]²⁺ and chloro-complexes.
1.Product Introduction
Copper(II) chloride naturally occurs as the rare mineral eriochalcite, forming azure crystals. Unlike many copper salts, it exhibits amphoteric behavior, reacting with both acids and bases. In solution, it displays a chameleon-like color shift: blue when hydrated, green when concentrated, due to complex equilibria between [Cu(H₂O)₆]²⁺ and chloro-complexes. Historically, it was pivotal in synthesizing ancient Egyptian blue pigments. Its crystalline lattice features distorted octahedral geometry around copper centers, enabling diverse coordination modes. This dual chemical personality—acting as both a Lewis acid and redox-active species—underpins its versatility in inorganic synthesis and materials science.

3.Product Feature And Application
Copper(II) chloride enables selective detection of thiols in laboratory analysis, forming yellow Cu(I)-thiolate complexes. It catalyzes oxidative coupling reactions in pharmaceutical synthesis, facilitating C-N bond formation. In electroplating, it serves as an electrolyte additive to refine copper deposition uniformity. Additionally, it acts as a desiccant indicator in moisture-sensitive packaging, shifting from blue to anhydrous green upon hydration. These niche applications exploit its coordination chemistry and reversible hydration behavior.
4.Product Details
Forms distorted octahedral crystals via Jahn-Teller effect, inherent in d⁹ copper(II) centers.
5.Product Qualification
We have received numerous government awards in China for our outstanding products and integrity in business operations. For exports, we hold REACH certification for multiple products, meeting EU import requirements for copper salt products. We are certified under the ISO 9001 Quality Management System and comply with RoHS standards. We can provide Safety Data Sheets (SDS) and all necessary documentation for every product.
6.Deliver,Shipping And Serving
In terms of packaging, we currently have two packaging options: bags and drums, their standard is 25kg. each pallet can load a total of 1 ton of goods. Some of the products will be in the ordinary bag on the basis of increasing the ton bag for uniform packaging, in the protection of the product at the same time to ensure the beauty of the goods. For some special products or special needs of customers, we can ensure the sealing and safety of the products by the form of barrel.
7.FAQ
What are the delivery terms available?
Generally, we commonly use FOB and CIF for delivery. If the customer has other delivery requirements, we can also discuss and negotiate.
