  • Applications

    Cyanine Green G Base, CAS 128-80-3, is primarily used as a colorant for inks, coatings, and plastics, providing a bright green shade for products and formulations. It is commonly incorporated into polymer systems and masterbatches as a color component. In analytical and research settings, the compound is considered a fluorescent dye or stain for marking and visualization using imaging techniques. Additionally, it can serve as a color indicator or marker for quality control and process monitoring, subject to formulation limits and local regulations.
