EDTA-4Na (Tetrasodium EDTA)
High-Performance Chelating Agent for Stable Micronutrients Formulations
Chelating Agent for Modern Fertilizer Formulations
EDTA-4Na (Tetrasodium EDTA) is a highly soluble sodium salt of ethylenediaminetetraacetic acid (EDTA), widely used as an effective chelating agent in agricultural, nutritional, and specialty chemical formulations.
With excellent solubility and strong metal-binding capability, EDTA-4Na helps maintain mineral stability and improve the availability of metal ions in various applications.
In agriculture, EDTA-4Na is commonly used as a key raw material for manufacturing EDTA chelated micronutrients, including EDTA Iron, EDTA Zinc, EDTA Manganese, and EDTA Copper.
Due to its alkaline characteristics and high solubility, EDTA-4Na is particularly suitable for formulations requiring improved pH compatibility and stable chelation performance.
Key Benefits
Strong Chelating Performance
EDTA-4Na effectively binds metal ions and helps prevent unwanted precipitation or reactions.
Excellent Water Solubility
Compared with EDTA Acid, EDTA-4Na provides superior solubility, making it suitable for:
Suitable for Alkaline Formulations
With a typical pH range of 10.5–11.5, EDTA-4Na is suitable for applications requiring alkaline compatibility and stable formulation performance.
