Fast Green FCF
Fast Green FCF (CAS: 2353-45-9) is a dark green triarylmethane colorant that delivers a brilliant, stable green shade in many media. It is permitted as a food colouring in several markets and is widely used in beverages, desserts, candies, and baked goods, as well as in pharmaceutical and cosmetic coloration where regulations allow. Beyond food use it is an important biological stain, serving as a cytoplasmic counterstain in histology and electrophoresis work because it resists fading better than similar dyes such as light green SF. The dye has high tinctorial strength, good light stability, and consistent shade from batch to batch. Customers choose it for food, pharmaceutical, and laboratory applications requiring a vivid, durable green colorant.
• Food coloration: imparts vivid green shades to beverages, confectionery, desserts, and baked products where regulations permit its use.
• Biological staining: cytoplasmic counterstain in Masson trichrome and Papanicolaou-type histology protocols with excellent resistance to fading.
• Electrophoresis and education: used to stain proteins and gels and as a reliable reagent in teaching laboratories.
• Pharmaceuticals and cosmetics: colorant for dosage forms and personal-care products where approved, providing stable and attractive shades.
