2-Naphthalenesulfonic acid, 6-hydroxy-5-[2-[4-[2-[4-(phenylamino)-3-sulfophenyl]diazenyl]-1-naphthalenyl]diazenyl]-, sodium salt (1:2)

Description:

2-Naphthalenesulfonic acid, 6-hydroxy-5-[2-[4-[2-[4-(phenylamino)-3-sulfophenyl]diazenyl]-1-naphthalenyl]diazenyl]-, sodium salt (1:2), commonly referred to as a dye or pigment, is a complex organic compound characterized by its azo dye structure. This compound features multiple aromatic rings, which contribute to its stability and color properties. The presence of sulfonic acid groups enhances its solubility in water, making it suitable for various applications in textiles and other industries. The sodium salt form indicates that it is ionized, which further increases its solubility and reactivity. The compound exhibits strong chromophoric properties due to the azo (-N=N-) linkage, which is responsible for its vibrant coloration. Additionally, the presence of hydroxyl and amino groups can influence its reactivity and interaction with other substances. Overall, this compound is notable for its use in dyeing processes, particularly in applications requiring bright and stable colors. Safety and handling precautions should be observed due to potential toxicity associated with azo dyes.
