Description

Ethylenediaminetetraacetic Acid Diammonium Salt Monohydrate is a high-purity, water-soluble chelating agent widely used in analytical chemistry and industrial processes. Its primary value lies in its ability to form stable, water-soluble complexes with a wide range of di- and trivalent metal ions, effectively sequestering them from solution. This product is essential for researchers, analytical laboratories, and manufacturers in sectors such as pharmaceuticals, cosmetics, and water treatment where precise metal ion control is critical.

Application

• Analytical Chemistry: Used as a primary standard and complexometric titrant for the determination of metal ions via EDTA titration methods.
• Pharmaceutical & Cosmetic Formulations: Acts as a stabilizer and chelating agent to inactivate trace metal contaminants that can catalyze oxidation and degrade active ingredients.
• Industrial Water Treatment: Employed in boiler and cooling water systems to control scale formation by sequestering calcium, magnesium, and other hardness ions.
• Laboratory Reagent: Serves as a key component in buffer solutions and metal-free media for molecular biology and biochemical assays.
• Cleaning & Detergent Additive: Enhances the efficiency of cleaning formulations by softening water and improving surfactant performance.
• Pulp & Paper Industry: Used to control metal ion concentrations during bleaching and processing, improving product brightness and quality.
