Product Description

 

Tetrasodium Edetate (EDTA Tetrasodium Salt)    
Ultra-High Solubility Chelating Agent for Industrial and Commercial Applications   

Tetrasodium EDTA (C10H12N2Na4O8·4H2O), systematically named tetrasodium 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetate tetrahydrate, is a white crystalline powder or granules with exceptional water solubility (>500 g/L at 25°C). This hydrated form exhibits strong alkalinity in aqueous solutions (pH 10-12 for 1% solution) and high stability under ambient conditions. Fully compliant with USP, EP, and FCC standards, it is a non-hygroscopic, non-flammable compound with broad regulatory acceptance for industrial and consumer applications.   EDTA Tetrasodium Salt's versatility is a high-performance, eco-friendly chelator for traditional industries and cutting-edge technologies.
