Description

Ethylene Glycol-Bis(β-Aminoethyl Ether)-N,N,N',N'-Tetraacetic Acid Tetrasodium Salt is a high-purity, water-soluble chelating agent and a specialized derivative of EGTA. This compound is critical for applications requiring the precise buffering and sequestration of calcium ions with minimal interference from magnesium, offering superior selectivity in complex matrices. It is an essential reagent for researchers and manufacturers in life sciences, analytical chemistry, and industrial processes where controlled metal ion concentration is paramount for quality and reproducibility.

Application

• Biochemical & Molecular Biology Research: A key component in buffer systems for calcium-dependent enzyme studies, cell culture, and protein purification where specific calcium chelation is required.
• Diagnostic Reagent Formulation: Used in the production of clinical diagnostic kits and assays to control calcium levels and prevent interference.
• Pharmaceutical Manufacturing: Employed as a stabilizing agent and metal ion scavenger in the synthesis and formulation of active pharmaceutical ingredients (APIs).
• Analytical Chemistry: Serves as a masking agent in complexometric titrations and spectroscopic analysis to improve selectivity for calcium determination.
• Industrial Process Chemistry: Acts as a sequestrant in various chemical manufacturing processes to inhibit metal-catalyzed degradation or side reactions.
• Cosmetic & Personal Care: Utilized in formulations as a chelating agent to enhance stability and shelf-life by binding trace metal impurities.
