2,7-Naphthalenedisulfonic acid, 3-[2-[4-(acetylamino)phenyl]diazenyl]-4-hydroxy-5-[[(4-methylphenyl)sulfonyl]amino]-, sodium salt (1:2)

Description:

2,7-Naphthalenedisulfonic acid, 3-[2-[4-(acetylamino)phenyl]diazenyl]-4-hydroxy-5-[[(4-methylphenyl)sulfonyl]amino]-, sodium salt (1:2), commonly referred to by its CAS number 10130-48-0, is a complex organic compound characterized by its azo dye structure. This substance features a naphthalene backbone with multiple sulfonic acid groups, which enhances its solubility in water and contributes to its application in dyeing processes. The presence of the azo group (-N=N-) indicates that it can exhibit vivid colors, making it useful in various dye applications, particularly in textiles and inks. The acetylamino and sulfonylamino substituents further modify its chemical properties, potentially influencing its reactivity and interaction with other compounds. As a sodium salt, it is likely to be more soluble in aqueous solutions, facilitating its use in various industrial applications. Overall, this compound exemplifies the characteristics typical of synthetic dyes, including stability, solubility, and color intensity, while also being subject to regulatory considerations due to its azo structure.
