CAS 85-83-6: Solvent Red 24

Description: Solvent Red 24, with the CAS number 85-83-6, 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 red color. This compound is known for its good solubility in organic solvents, making it suitable for use in non-aqueous systems. Solvent Red 24 exhibits stability under normal conditions, but like many azo dyes, it can undergo degradation when exposed to strong light or heat. It is important to handle this substance with care, as some azo dyes have been associated with potential health risks, including skin irritation or allergic reactions. Additionally, environmental considerations are crucial, as the disposal of azo dyes can lead to contamination if not managed properly. Overall, Solvent Red 24 is valued for its coloring properties but requires responsible usage and handling in industrial applications.
