(7-Hydroxy-8-((4-sulpho-1-naphthyl)azo)naphthalene-1,3-disulphonato(3-))aluminium

Description:
(7-Hydroxy-8-((4-sulpho-1-naphthyl)azo)naphthalene-1,3-disulphonato(3-))aluminium, commonly referred to as a dye, is characterized by its complex structure that includes multiple functional groups, such as hydroxyl, sulfonate, and azo groups. This compound is typically used in various applications, including textiles and biological staining, due to its vibrant color and ability to bind to different substrates. The presence of sulfonate groups enhances its solubility in water, making it suitable for aqueous applications. The azo linkage contributes to its stability and color properties, while the aluminum component may serve as a mordant, improving the dye's adherence to fibers. This substance is often evaluated for its environmental impact and safety, as some azo dyes can release aromatic amines, which may pose health risks. Overall, its unique chemical structure and properties make it a valuable compound in dye chemistry and related fields.
