  • Applications

    Vat Blue 6, CAS 130-20-1, is a vat dye primarily used for textile coloration, especially on cellulose fibers such as cotton and viscose, applied via a reduction-oxidation cycle to form a durable blue shade; beyond direct textile dyeing, it is commonly employed as an intermediate in the production of other vat dyes and colorant systems; it is also incorporated into coating formulations and printing inks for the textile and broader colorant industries; in polymer and plastics applications, Vat Blue 6 can serve as a precursor for pigment synthesis and colorant formulations; and in industrial manufacturing generally it is treated as a colorant component in various formulation systems, subject to local regulations and formulation limits.
