  • Applications

    Ammonium ferric pentetate is an iron(III) chelate that acts primarily as a metal-sequestering agent. It is used to bind trace metals in formulations and industrial processes, including detergents and cleaners to prevent metal-catalyzed degradation and scale formation. In polymers and plastics, it serves as a stabilizer and processing aid to suppress metal-catalyzed oxidation and improve processing stability. In coatings and inks, it helps control metal ion contamination and can enhance pigment dispersion and storage stability. In agriculture, its iron complex form can act as a micronutrient chelate fertilizer, supplying iron to iron-deficient soils. In the laboratory, it may be used as a reagent in complexometric titrations and other metal-chemistry applications.
