Description

N,N'-[1,2-Ethanediylbis[Oxy(4-Fluoro-2,1-Phenylene)]]Bis[n-(Carboxymethyl)Glycine] Tetrapotassium Salt is a high-purity, water-soluble chelating agent specifically designed for demanding industrial and research applications. Its molecular structure, featuring multiple carboxylate groups and a fluorinated aromatic backbone, provides exceptional metal ion binding capacity, particularly for transition and lanthanide series metals. This compound is essential for manufacturers and researchers in sectors requiring precise control over metal ion activity, such as advanced material synthesis, analytical chemistry, and specialized chemical processes.

Application

• Analytical Chemistry Reagent: Used as a selective chelating agent in complexometric titrations and as a masking agent in spectrophotometric analysis for trace metal determination.
• Pharmaceutical Intermediate: Serves as a key building block or complexing agent in the synthesis of contrast agents for medical imaging (MRI) and other diagnostic pharmaceuticals.
• Material Science & Catalysis: Employed in the preparation of metal-organic frameworks (MOFs), homogeneous catalysts, and other functional materials where controlled metal ion incorporation is critical.
• Industrial Water Treatment: Acts as a high-performance scale inhibitor and sequestrant in boiler water and cooling systems, particularly where standard polycarboxylates are insufficient.
• Electroplating & Surface Finishing: Functions as a brightener and complexant in specialty electroplating baths to improve deposit quality and process stability for non-standard metals.
• Research & Development: A valuable tool in biochemical and inorganic chemistry research for studying metal-ligand interactions, enzyme inhibition, and model systems.
