General Description
Fast Sulphon Black F is a sulfonated azo dye that is characterized by high tinting power, water solubility and stable staining behavior. It can be used in histological applications to increase the sharpness and dark contrast of microscopic images of samples of tissues. It finds application in analytical chemistry as a complexometric indicator in EDTA titrations, especially in determining copper ions by a characteristic color change. Besides laboratories, this dye is also very useful in the textile industry, where it gives a deep and long-lasting black color to both natural and artificial textiles. This renders it a favorite to both industrial manufacturers and laboratories due to its flexibility, sturdiness and its cost-effectiveness.
