Ethylene Diamine Tetraacetic Acid Tetrasodium Salt (EDTA Tetrasodium Salt, CAS: 10378-23-1) is a fundamental chemical compound with extensive applications across numerous industries. Understanding its scientific properties is key for procurement managers and R&D scientists seeking to optimize formulations and processes. As a prominent chemical supplier, we provide valuable insights into this versatile molecule.

Chemical Structure and Properties

EDTA Tetrasodium Salt is an organic compound belonging to the aminopolycarboxylic acid family. Its chemical structure features an ethylenediamine backbone with four acetate groups, each capable of coordinating with a metal ion. As a tetrasodium salt, it dissociates in water to form EDTA anions and sodium cations. This structure grants it a high affinity for a wide range of metal ions, forming stable, water-soluble chelate complexes. Key properties include:

  • High Water Solubility: Facilitates its incorporation into aqueous formulations.
  • Chelating Ability: Its primary function is to bind and sequester metal ions, effectively removing them from active participation in chemical reactions.
  • pH Dependence: While all EDTA salts are chelators, the tetrasodium salt is particularly effective in alkaline conditions.
  • White Crystalline Powder: Its common physical form allows for easy handling and measurement.

Scientific Applications and Mechanisms

The ability of EDTA Tetrasodium Salt to complex metal ions makes it indispensable in various scientific and industrial applications:

  • Analytical Chemistry: Used in titration to determine the concentration of metal ions.
  • Biochemistry: Acts as an anticoagulant by chelating calcium ions, which are essential for blood clotting. It's also used in buffer solutions and as a stabilizer in biological assays.
  • Chemical Synthesis: It can be employed to control the reactivity of metal catalysts or to remove trace metal impurities.
  • Industrial Processes: Its role in water treatment, detergent enhancement, and stabilizing cosmetic formulations relies on its consistent ability to manage metal ion activity.
