Our Cuprous Chloride (chemical name: Copper(I) Chloride) is a versatile inorganic compound designed for industrial-grade applications, with strict quality controls to ensure consistency and performance.
Cuprous Chloride has a molecular formula of CuCl and a CAS number of 7758-89-6, with a molecular weight of 99. It presents as a white crystalline solid or fine crystalline powder—distinctive traits that make it easy to identify and handle in industrial settings.
Key physical and chemical properties include:
• Density of 4.41g/cm³, ensuring stability in high-pressure processes
• Melting point of 430°C and boiling point of 1490°C, suitable for high-temperature industrial operations
• Sensitivity to environmental factors: prone to oxidation in air (converting to higher copper salts) and decomposes into a brown substance when exposed to light
• Solubility profile: dissolves in acids and ammonia, is slightly soluble in water, and insoluble in ethanol and acetone—ideal for processes requiring controlled solubility.
We adhere to strict purity standards to meet industrial requirements:
• Minimum CuCl content: 98% (ensuring core performance)
• Maximum impurity limits:
◦ Copper(II) Chloride (CuCl₂): ≤1%
◦ Heavy metals (Pb, As, Cd): each ≤0.003% (reducing risks of contamination in sensitive applications)
◦ Iron (Fe): ≤0.005%
◦ Sulfate (SO₄): ≤0.3%
◦ Acid-insoluble matter (A.I.M): ≤0.03% (preventing residue buildup in processes like electroplating).
Our Cuprous Chloride offers unique advantages that make it a top choice for businesses across sectors, combining performance, cost-efficiency, and sustainability.
The ≥98% purity of our Cuprous Chloride eliminates unwanted side reactions caused by impurities. This reliability is critical for applications like semiconductor manufacturing (where even trace contaminants can damage components) and pharmaceutical production (where purity directly impacts product safety).
Compared to other copper-based compounds, our Cuprous Chloride delivers exceptional value. Its high purity reduces waste (fewer failed batches) and its versatility means it can replace multiple chemicals in different processes—lowering inventory and procurement costs for businesses.
Cuprous Chloride is non-toxic and environmentally friendly, aligning with global sustainability goals. It avoids harmful byproducts in processes like agricultural fungicide use (protecting soil and water quality) and industrial catalysis (reducing carbon footprints for manufacturers aiming to cut emissions).
Unlike single-use chemicals, our Cuprous Chloride adapts to diverse applications—from electronics to agriculture. This versatility lets businesses streamline their supply chains, relying on one trusted product for multiple operational needs.
Cuprous Chloride’s unique properties make it indispensable in key industries, with applications ranging from manufacturing to agriculture.
In electronics, it is a core material for producing critical components:
• Printed Circuit Boards (PCBs): Its low water solubility ensures stable adhesion of conductive layers, preventing short circuits.
• Semiconductors: High purity minimizes contamination, supporting the production of microchips and other precision electronic parts.
As a natural fungicide, Cuprous Chloride controls fungal diseases in crops (e.g., blight in fruits and vegetables). Its antifungal properties protect plant health without harming beneficial organisms, making it suitable for organic and conventional farming.
It acts as a catalyst in polymer production, including polyethylene and polypropylene—speeding up reaction times while maintaining polymer quality. It also serves as a petroleum deodorization and desulfurization agent, removing unwanted odors and sulfur compounds from fuel products.
In pharmaceuticals, it is used in synthesizing drugs and medicines, where purity ensures compliance with health regulations. In metal extraction, it aids in recovering gold and copper from ores, improving the efficiency of mining operations.
It is also employed in pigment production (creating stable, long-lasting colors), corrosion control (protecting metal surfaces from rust), and as an analytical reagent in laboratory testing.
To maintain stability, store Cuprous Chloride in a cool, dry, and dark space—away from direct sunlight (to prevent decomposition) and moisture (to avoid clumping or oxidation). Sealed containers are recommended to minimize air exposure, preserving purity for extended periods.
Cuprous Chloride is soluble in acids and ammonia, making it compatible with these solvents for processes like electroplating or catalysis. It is insoluble in ethanol and acetone, so these solvents can be used to clean equipment without dissolving the product.
