Description

Copperdisodiumedtatrihydrate CAS NO 73637-19-1 is a chelated copper complex of ethylenediaminetetraacetic acid (EDTA). This compound is valued for its ability to provide bioavailable copper in a stable, soluble form, preventing precipitation and antagonistic interactions in complex systems. It is essential for manufacturers in the agricultural micronutrient, industrial water treatment, and specialty chemical synthesis sectors who require a consistent and effective source of chelated copper.

Application

• Agricultural Micronutrient Fertilizers: As a highly effective source of copper in chelated liquid or granular fertilizers to correct deficiencies in crops.
• Industrial Water Treatment: Used in cooling and boiler water systems as a metal ion sequestrant to control scale and corrosion.
• Chemical Synthesis & Catalysis: Serves as a precursor or catalyst in various organic synthesis and polymerization reactions.
• Animal Nutrition: Incorporated into premixes as a source of bioavailable copper in animal feed.
• Pulp & Paper Industry: Acts as a stabilizer and chelating agent in bleaching and pulping processes.
• Textile Processing: Utilized in dyeing and printing processes to improve color fastness and quality.

Quality Control

Our Copperdisodiumedtatrihydrate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and chelation efficiency. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent absorption of atmospheric moisture and potential caking.
