Description

Zinc Edta CAS NO 55448-21-0 is a high-purity, water-soluble chelate of zinc and ethylenediaminetetraacetic acid (EDTA), designed for applications requiring a highly bioavailable and stable source of zinc. This compound is essential for correcting zinc deficiencies in systems where other zinc sources may precipitate or become unavailable. It is a critical ingredient for manufacturers in the agricultural, nutritional, and industrial sectors seeking reliable micronutrient delivery and metal ion control.

Application

• Agricultural Micronutrient Fertilizers: As a highly effective foliar spray or soil additive to prevent and correct zinc deficiency in a wide range of crops, enhancing yield and plant health.
• Animal Nutrition & Feed Premixes: Incorporated into mineral premixes for livestock, poultry, and aquaculture to ensure optimal zinc bioavailability for growth, immune function, and reproduction.
• Dietary Supplements & Food Fortification: Used in vitamin/mineral supplements and fortified foods (e.g., cereals, beverages) as a stable, bioavailable source of essential zinc.
• Industrial Process Stabilizer: Acts as a chelating agent in chemical processes, textiles, and personal care formulations to sequester metal ions that can cause unwanted catalysis, discoloration, or spoilage.
• Laboratory & Analytical Reagent: Employed in research and quality control laboratories as a standard or buffer component in complexometric titrations and trace metal analysis.
• Cosmetic and Personal Care: Functions as a stabilizing agent in formulations to improve shelf-life and product integrity by controlling trace metal contaminants.

Quality Control

Our Zinc Edta is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, potency, and purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, heavy metal content, and physical properties. Our production can align with relevant industry standards for agricultural and nutritional applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking and reduced stability.
