Core Chemical & Physical Characteristics
Copper Chloride Basic, often referred to as cupric chloride basic or copper oxychloride, is a high-performance chemical with the molecular formula Cu₂(OH)₃Cl and CAS number 1332-40-7. Its molecular weight of 213.57 contributes to its robust chemical stability, making it a reliable choice for long-term storage and varied industrial applications.
This compound presents as green crystalline or dark green crystalline powder—an easily recognizable trait that distinguishes it from other copper-based products. It maintains exceptional stability in air, resisting degradation even when exposed to normal atmospheric conditions. A key advantage is its low water absorption: unlike many powdered chemicals, it does not clump easily, staying free-flowing to simplify handling during production. Additionally, the surface of its solid particles is neutral, which prevents unwanted reactions with other ingredients in formulations—a critical benefit for precise manufacturing processes.
As a leading copper chloride producer, we uphold rigorous quality control to ensure consistency across every batch. Our Copper Chloride Basic meets the following industry-leading specifications:
• Copper (Cu) content: Minimum 58% (guarantees effectiveness in feed additives and intermediate applications)
• Arsenic (As): Maximum 0.001% (aligns with global safety rules for agricultural and pharmaceutical use)
• Lead (Pb): Maximum 0.001% (low heavy metal content reduces environmental and health risks)
• Cadmium (Cd): Maximum 0.0003% (meets strict purity demands for sensitive industries like pharmaceuticals)
Reduced Waste via Strong Stability
Its air stability and low water absorption eliminate losses from clumping or degradation. This means longer shelf life and consistent performance in every batch—you won’t need to discard unused product due to moisture damage.
The neutral particle surface allows seamless blending into pesticide mixes, pharmaceutical intermediates, and wood preservative solutions. It won’t disrupt the pH or chemical balance of your formulations, ensuring your end products meet exact specifications.
With ultra-low levels of heavy metals (As, Pb, Cd), our Copper Chloride Basic adheres to international safety standards for agriculture, pharmaceuticals, and feed. This removes barriers for businesses targeting global markets.

It acts as a key raw material in manufacturing high-efficiency pesticides. Its stable structure boosts the durability of pesticide formulations, providing long-lasting crop protection without harming soil health.
In pharmaceuticals, it serves as a reliable intermediate for synthesizing specific medications. Its high purity (low heavy metals) meets the strict requirements for pharmaceutical-grade materials.
When added to wood preservatives, it protects timber from rot, fungi, and insect infestations. Its stability ensures the preservative remains effective even in outdoor or high-moisture environments.
As a feed additive, it delivers essential copper to livestock diets. The minimum 58% Cu content ensures optimal nutrient intake, supporting animal growth and health while complying with animal feed safety regulations.
