  • Applications

    Fast Green FCF (CAS 2353-45-9) is a water-soluble dye used primarily as a colorant in a range of industrial and laboratory applications. In the food and beverage sector, it serves as a green coloring agent in regions where permitted; in cosmetics and personal care it is used to impart green hues to products such as soaps and creams. In the biomedical and analytical laboratory, it functions as a histology or microscopy stain and as a qualitative indicator in staining protocols. It is also employed as a colorant in coatings and inks, and may be used as a dye additive in polymers and plastics formulations. Additionally, it is used as a dye tracer in some analytical or quality-control workflows. Subject to local regulations and formulation limits.
