  • Applications

    N,N-Bis(2-hydroxy)-p-phenylenediamine sulfate (CAS number: 54381-16-7) is primarily used as a colorant and pigment synthesis intermediate, serving as a precursor for color systems in textiles, leather, and cosmetics. It is also employed as a starting material for stabilizers and antioxidants in polymers and rubber, helping to improve thermal and weathering stability of plastics and elastomers. In coatings and inks, the compound functions as a color precursor and can participate in binding systems to fix pigments to surfaces. Additionally, it is considered a water-soluble intermediate for specialty color formulations and related additive chemistries, subject to local regulations and formulation limits.
