Description

Bis(2-Aminoethyl) Ether N,N,N',N'-Tetraacetic Acid is a high-purity, multidentate chelating agent and a specialized derivative of ethylenediaminetetraacetic acid (EDTA). This compound is valued for its strong and selective binding affinity for a wide range of di- and trivalent metal ions, forming exceptionally stable complexes. It is a critical reagent for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise metal ion control, stabilization, or removal in complex formulations and processes.

Application

• Pharmaceutical Synthesis & Formulation: Acts as a stabilizing agent and metal chelator in injectable drugs, biologics, and diagnostic reagents to prevent metal-catalyzed degradation.
• Biochemical & Molecular Biology Research: Used in buffer systems for enzyme assays, cell culture media, and nucleic acid purification to sequester contaminating metal ions that can inhibit reactions.
• Industrial Catalyst & Polymer Stabilization: Serves as a ligand for homogeneous catalysts and as an additive to prevent metal-induced oxidation and discoloration in polymers and specialty chemicals.
• Analytical Chemistry: Employed as a titrant in complexometric titrations and as a masking agent in spectrophotometric analysis to improve selectivity for target metals.
• Water Treatment & Detergent Formulations: Functions as a high-performance sequestrant for scale-forming cations like calcium and magnesium in industrial water systems and cleaning products.
• Electroplating & Surface Treatment: Used in plating baths to complex metal ions, ensuring smooth, even deposition and improved quality of metal coatings.
