Description

(Ethylenedinitrilo)Tetrakis(Methanesulfonic Acid Sodium) Salt is a high-purity, water-soluble chelating agent and analytical reagent. Its primary value lies in its exceptional ability to form stable complexes with a wide range of metal ions, making it indispensable for processes requiring precise metal control or analysis. This compound is essential for manufacturers and research laboratories in the pharmaceutical, chemical synthesis, and analytical chemistry sectors.

Application

• Pharmaceutical Synthesis & Purification: Acts as a metal scavenger and catalyst ligand in the synthesis of active pharmaceutical ingredients (APIs) to control metal impurities.
• Analytical Chemistry: Used as a complexometric titrant and masking agent in titrations (e.g., EDTA-type titrations) and spectroscopic analysis for determining metal ion concentrations.
• Industrial Water Treatment: Functions as a scale and corrosion inhibitor in boiler and cooling water systems by sequestering calcium, magnesium, and other metal ions.
• Chemical Manufacturing: Serves as a stabilizer and chelating agent in polymerization processes, dye production, and agrochemical formulations.
• Laboratory Research: A key reagent for studying metal-ligand interactions, buffer preparation for metal-sensitive biochemical assays, and sample preparation for ICP-MS or AAS.
• Cleaning Formulations: Incorporated into industrial and institutional cleaning products to enhance surfactant performance by controlling water hardness.
