Description

Fe(II)-EDTA is a stable, water-soluble chelate of ferrous iron and ethylenediaminetetraacetic acid, essential for providing bioavailable iron in systems where standard iron salts are prone to precipitation and oxidation. This compound is critical for applications requiring precise iron delivery without unwanted side reactions or loss of activity. It is a fundamental material for the agricultural, nutritional, and industrial sectors, where controlled iron availability directly impacts product performance and process efficiency.

Application

• Agricultural Micronutrient Fertilizer: Used in foliar sprays and hydroponic nutrient solutions to correct and prevent iron chlorosis in crops, especially in high-pH soils.
• Nutraceutical & Food Fortification: Serves as a highly bioavailable iron source in dietary supplements and food products like cereals and infant formula.
• Industrial Process Chemistry: Acts as a catalyst or stabilizing agent in various chemical synthesis and polymerization processes.
• Water Treatment & Chelation: Employed to sequester metal ions in boiler water and industrial cleaning formulations to prevent scale and corrosion.
• Pharmaceutical Intermediate: Used in the synthesis of certain pharmaceutical compounds requiring a bioavailable iron complex.
• Laboratory Research & Reagent: Functions as a standard and reagent in biochemical and environmental research for studying iron metabolism and chelation.

Quality Control

Our Fe(II)-EDTA is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and iron content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, heavy metals, and loss on drying. Our quality commitment supports applications requiring consistency from agricultural to pharmaceutical grades.

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); ensure the container is sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking and reduced stability.
