2-Naphthalenesulfonic acid, 7,7′-(carbonyldiimino)bis[4-hydroxy-3-[(2-methyl-4-sulfophenyl)azo]-, sodium salt

Description:
2-Naphthalenesulfonic acid, 7,7′-(carbonyldiimino)bis[4-hydroxy-3-[(2-methyl-4-sulfophenyl)azo]-, sodium salt, commonly referred to as a dye or pigment, is a complex organic compound characterized by its azo dye structure. This compound features a naphthalene sulfonic acid moiety, which enhances its solubility in water, making it suitable for various applications in textiles and food coloring. The presence of multiple functional groups, including sulfonic acid and hydroxyl groups, contributes to its reactivity and ability to form strong bonds with substrates. The sodium salt form indicates that it is likely to be more soluble in aqueous solutions, which is advantageous for its use in dyeing processes. Additionally, the azo linkage provides vibrant coloration, making it valuable in the dye industry. Its stability under various conditions and the ability to produce bright hues are key characteristics that define its utility in commercial applications. Safety and environmental considerations are essential when handling such compounds, as they may pose risks if not managed properly.
