CAS 596-03-2: Solvent Red 72

Description: Solvent Red 72, with the CAS number 596-03-2, is an organic dye primarily used as a colorant 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 red color. This compound is known for its excellent solubility in organic solvents, making it suitable for use in non-aqueous systems. Solvent Red 72 exhibits good thermal stability and lightfastness, which are important properties for maintaining color integrity in end products. 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, its use is often regulated, and safety data sheets should be consulted to ensure proper handling and disposal. Overall, Solvent Red 72 is valued for its coloring properties but requires careful consideration regarding safety and environmental impact.
