Dichloro copper dihydrate, systematically copper(II) chloride dihydrate (CuCl2·2H2O), features a central copper(II) ion coordinated by two chloride ligands and two water molecules in a distorted octahedral geometry. This hydration stabilizes the crystal lattice, forming distinctive blue-green crystals.
1.Product Introduction
Dichloro copper dihydrate, systematically copper(II) chloride dihydrate (CuCl2·2H2O), features a central copper(II) ion coordinated by two chloride ligands and two water molecules in a distorted octahedral geometry. This hydration stabilizes the crystal lattice, forming distinctive blue-green crystals. The compound readily dehydrates reversibly upon heating, releasing water vapor. Its Lewis acidity enables catalytic activity in organic transformations and facilitates the synthesis of copper complexes. The dihydrate form enhances solubility in polar solvents compared to the anhydrous salt, making it a versatile precursor in materials science and coordination chemistry research.

3.Product Feature And Application
Dichloro copper dihydrate (CuCl2·2H2O) finds niche applications beyond common industrial uses. It serves as an effective wood preservative, acting as a fungicide and insecticide to protect timber from decay. In dye synthesis, it catalyzes the production of phthalocyanine blue and green pigments. The compound is also employed in pyrotechnics to create vivid blue-green color effects in fireworks and flares. Additionally, it functions as a mordant in textile dyeing, enhancing color fastness by forming complexes with natural fibers. These specialized uses leverage its copper content and reactivity in controlled environments.
4.Product Details
Dichloro copper dihydrate (CuCl2·2H2O) has a density of 2.51 g/cm³ and dissolves readily in water, ethanol, and acetone. It exhibits strong corrosive properties, damaging skin and metals. Decomposes near 100°C, releasing hydrochloric acid gas. Forms acidic aqueous solutions (pH ~3.5–4.0). Requires chemical-resistant gloves and ventilation during handling.
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.
