Overview
High-purity copper calcium basic sulfate is a chemical compound primarily used in agriculture for its fungicidal and bactericidal properties. It is a derivative of copper sulfate and calcium, combining the benefits of both elements in a stable form. The compound is known for its effectiveness against a wide range of plant pathogens, making it a popular choice in integrated pest management systems. Its high purity ensures minimal impurities, which is crucial for agricultural applications where residue and environmental impact are concerns. The compound is typically applied as a foliar spray or soil treatment, providing long-lasting protection against fungal and bacterial infections.
Physical and Chemical Properties
High-purity copper calcium basic sulfate appears as a light blue to green powder or crystalline solid. It is slightly soluble in water but insoluble in most organic solvents. The compound is stable under normal storage conditions but may decompose when exposed to high temperatures or strong acids. Its molecular formula, CuCa(SO4)(OH)2, reflects the combination of copper, calcium, sulfate, and hydroxide ions. This structure contributes to its fungicidal activity by releasing copper ions gradually, ensuring prolonged effectiveness. The compound's density is approximately 3.5 g/cm³, and it decomposes before reaching a melting point.
Main Applications
The primary application of high-purity copper calcium basic sulfate is in agriculture, where it serves as a broad-spectrum fungicide and bactericide. It is particularly effective against diseases like downy mildew, blight, and leaf spot in crops such as grapes, tomatoes, and potatoes. The compound is also used in wood preservation to protect against fungal decay and insect damage. In addition to its agricultural uses, it is sometimes employed in water treatment and as a component in certain industrial processes. Its ability to release copper ions in a controlled manner makes it a preferred choice for sustainable pest management practices.
Safety and Storage
High-purity copper calcium basic sulfate requires careful handling to ensure safety. Direct contact with skin or eyes can cause irritation, and inhalation of dust should be avoided. Personal protective equipment (PPE), such as gloves and masks, is recommended when handling the compound. Storage conditions should be cool and dry, away from moisture and incompatible substances like strong acids. Proper labeling and secure containers are essential to prevent accidental exposure. Disposal should follow local regulations to minimize environmental impact.
B2B Procurement Guide
When procuring high-purity copper calcium basic sulfate, B2B buyers should prioritize suppliers with certifications for agricultural chemicals. Key factors to consider include purity levels, batch consistency, and compliance with regional safety standards. Requesting material safety data sheets (MSDS) and certificates of analysis (CoA) is advisable. Price ranges typically fall between $10 and $20 per kilogram, depending on purity and order volume. Bulk purchases may qualify for discounts. It's also important to evaluate logistics options, as the compound may require specific transportation conditions to maintain stability.
