CAS 4197-07-3: Chromotrope 2R
Description:Chromotrope 2R, with the CAS number 4197-07-3, is a synthetic dye belonging to the azo dye class, characterized by its vibrant red color. It is primarily used in various applications, including textile dyeing, paper coloring, and as a biological stain in microscopy. The dye exhibits good solubility in water, which makes it suitable for aqueous applications. Chromotrope 2R is known for its stability under light and heat, although, like many azo dyes, it may undergo degradation under extreme conditions. Its chemical structure features azo (-N=N-) linkages, which are responsible for its color properties. While it is effective for its intended uses, safety considerations are important, as some azo dyes can release aromatic amines upon degradation, which may pose health risks. Therefore, handling Chromotrope 2R requires adherence to safety guidelines to minimize exposure. Overall, Chromotrope 2R is valued for its coloring properties in various industries, but awareness of its chemical behavior and safety profile is essential.
