CAS 6535-42-8: Solvent Red 3

Description: Solvent Red 3, with the CAS number 6535-42-8, is an organic dye primarily used as a coloring agent in various applications, including plastics, inks, and coatings. It belongs to the azo dye family, characterized by the presence of one or more azo groups (-N=N-), which contribute to its vibrant color. Solvent Red 3 is known for its solubility in organic solvents, making it suitable for non-aqueous systems. The compound exhibits good thermal stability and lightfastness, which are important properties for maintaining color integrity in end products. However, like many azo dyes, it may pose environmental and health concerns, as some azo compounds can release aromatic amines upon degradation. Therefore, its use is often regulated in certain applications. Safety data sheets typically indicate that it should be handled with care, as it may cause skin irritation or allergic reactions. Overall, Solvent Red 3 is valued for its coloring properties but requires responsible handling and usage in accordance with safety guidelines.
