Fast Sulfon Black F

Description:

Fast Sulfon Black F, with the CAS number 3682-47-1, is a synthetic dye belonging to the azo dye class, commonly used in textile and leather industries for its deep black coloration. This compound is characterized by its high solubility in water, which facilitates its application in various dyeing processes. Fast Sulfon Black F exhibits excellent light and wash fastness properties, making it suitable for use in products that require durability and resistance to fading. The dye is typically applied to cellulose fibers, such as cotton, and can also be used on synthetic fibers with appropriate mordants. Its chemical structure includes sulfonic acid groups, which enhance its affinity for fibers and contribute to its solubility. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of aromatic amines upon degradation. Therefore, proper handling and disposal practices are essential when working with this substance in industrial applications.

Fast Sulphon Black F

CAS: 3682-47-1

Fast Sulphon Black F is a stable, water-soluble dye that can be used for electrochemical measurements. It is an irreversible oxidation agent that has been shown to oxidize organic solvents and metal ions. The kinetic of the reaction with sodium salts was found to be first order in Fast Sulphon Black F and second order in sodium salt. This dye also has a potential use as a redox indicator in wastewater treatment systems. Fast Sulphon Black F is soluble in organic solvents, which may make it useful for optical sensors.
