Description

Edta Disodium Cupric Salt is a stable, water-soluble chelate complex of copper and ethylenediaminetetraacetic acid (EDTA). This compound is specifically engineered to provide a bioavailable and controlled source of copper ions, which is critical for numerous industrial and biochemical processes. It is essential for manufacturers in the agriculture, animal nutrition, and specialty chemical sectors who require a consistent, high-purity copper source that remains stable in complex formulations.

Application

• Agricultural Micronutrient Fertilizers: As a highly effective and stable source of copper for correcting deficiencies in crops, enhancing plant growth and yield.
• Animal Feed Premixes: Used as a nutritional copper supplement in poultry, swine, and ruminant feed to support metabolic functions and overall health.
• Industrial Catalysis: Serves as a catalyst or catalyst precursor in various chemical synthesis and polymerization reactions.
• Water Treatment & Chelating Agent: Functions as a sequestrant in water treatment systems to control metal ion scaling and in cleaning formulations.
• Laboratory & Research Reagent: Employed in biochemical research and analytical chemistry as a standard or buffer component.
• Electroplating Solutions: Acts as a stabilizing agent in electroplating baths to improve the quality and uniformity of copper deposits.

Quality Control

Our Edta Disodium Cupric Salt is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and metal content, aligning with industry benchmarks for agricultural and nutritional grades. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

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); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
