Copper(II) chloride dihydrate is a naturally occurring mineral (eriochalcite) and synthetic coordination compound. It forms blue-green, deliquescent crystals with an orthorhombic lattice where Cu²⁺ ions exhibit distorted octahedral geometry due to Jahn-Teller effects. The hydrate stabilizes copper(II) in aqueous environments, facilitating hydrolysis that yields acidic solutions (pH ≈ 4).
1.Product Introduction
Copper(II) chloride dihydrate is a naturally occurring mineral (eriochalcite) and synthetic coordination compound. It forms blue-green, deliquescent crystals with an orthorhombic lattice where Cu²⁺ ions exhibit distorted octahedral geometry due to Jahn-Teller effects. The hydrate stabilizes copper(II) in aqueous environments, facilitating hydrolysis that yields acidic solutions (pH ≈ 4). Its environmental persistence and catalytic activity in atmospheric chlorine radical generation contribute to ozone depletion cycles. The compound’s reactivity with moisture necessitates airtight storage, as it readily absorbs water and may release corrosive HCl vapor under humid conditions, posing ecological and handling risks.

3.Product Feature And Application
Copper(II) chloride dihydrate serves as an agricultural fungicide, effectively controlling fungal pathogens in crops. In pyrotechnics, it acts as a blue flame colorant due to copper ion emission. The compound functions as a nuclease inhibitor in molecular biology, preserving RNA/DNA integrity during extraction. It also catalyzes oxidative coupling reactions in polymer synthesis, enabling conductive material production. Additionally, it stabilizes vitamin supplements by preventing oxidation and aids in analytical chemistry as a reagent for detecting phospholipids. These applications leverage its redox activity, coordination chemistry, and antimicrobial properties across diverse scientific and industrial fields.
4.Product Details
Copper(II) chloride dihydrate dehydrates between 100–130°C, forming anhydrous CuCl₂ (brown-yellow). Further heating above 300°C yields copper oxychlorides (e.g., Cu₂OCl₂, Cu₃O₂Cl₂), appearing black. This thermal decomposition involves stepwise water loss followed by oxygen incorporation, altering its crystalline structure and magnetic properties significantly.
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
