  • Applications

    Diammonium dithiodiglycolate (CAS 68223-93-8) is primarily considered an intermediate in organic synthesis and a sulfur-containing chelating/complexing agent for metal ions in various industrial formulations. It may serve as a building block for downstream chemical production and, due to its disulfide functionality, is evaluated as a stabilizer or antioxidant in polymer systems and coatings. The salt can function as a processing aid in specialty cleaning, electroplating, and metal-handling formulations where metal ion sequestration is beneficial. It is also explored as a source of sulfur functionality for crosslinking or coupling steps in formulation chemistry and may be used in niche industrial applications where sulfur-containing ingredients are appropriate, subject to local regulations.
