Dichloro copper hydrate denotes copper(II) chloride with variable water content, commonly existing as dihydrate (x=2) but forming higher hydrates. Its structure features copper(II) centers coordinated by chloride ions and water molecules in a dynamic equilibrium. This hydration significantly enhances solubility in water and polar solvents compared to anhydrous CuCl₂.
1.Product Introduction
Dichloro copper hydrate denotes copper(II) chloride with variable water content, commonly existing as dihydrate (x=2) but forming higher hydrates. Its structure features copper(II) centers coordinated by chloride ions and water molecules in a dynamic equilibrium. This hydration significantly enhances solubility in water and polar solvents compared to anhydrous CuCl₂. The compound exhibits strong hygroscopicity, readily absorbing atmospheric moisture. Its Lewis acidity and variable coordination environment make it a versatile precursor in inorganic synthesis and coordination chemistry. The hydrate form offers easier handling and controlled reactivity than the highly deliquescent anhydrous salt.

3.Product Feature And Application
Dichloro copper hydrate serves key roles in agriculture as a fungicidal spray for crops like grapes and tomatoes, combating fungal pathogens. It acts as an algaecide in water treatment systems, inhibiting microbial growth in industrial cooling towers. In analytical chemistry, it detects amines via colorimetric reactions. The compound also catalyzes hydrocarbon oxidation reactions in petrochemical refining and functions as a precursor for synthesizing copper-based nanomaterials. Its controlled reactivity and solubility make it valuable for these specialized applications, particularly where precise copper ion release is required for efficacy.
4.Product Details
Dichloro copper hydrate is a paramagnetic crystalline solid. Its dihydrate form appears as blue-green prismatic crystals. Upon dehydration, it transitions to a brownish-yellow anhydrous state. The compound exhibits efflorescence in dry air, gradually losing water molecules. Its magnetic susceptibility varies with hydration level, useful in material characterization studies.
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.
