4-[2-(2,4-Dihydroxyphenyl)diazenyl]-5-hydroxy-2,7-naphthalenedisulfonic acid

Description:
4-[2-(2,4-Dihydroxyphenyl)diazenyl]-5-hydroxy-2,7-naphthalenedisulfonic acid, commonly referred to as a type of azo dye, is characterized by its vibrant color and solubility in water, which makes it useful in various applications, particularly in the textile and food industries. This compound features a naphthalene backbone with multiple functional groups, including hydroxyl and sulfonic acid groups, which enhance its reactivity and solubility. The presence of the azo (-N=N-) linkage contributes to its chromophoric properties, allowing it to absorb visible light and impart color. Additionally, the hydroxyl groups can participate in hydrogen bonding, influencing the compound's interactions in solution. Its chemical structure suggests potential applications in dyeing processes, as well as in biological studies due to its ability to interact with various biomolecules. However, like many azo compounds, it may also raise environmental and health concerns, necessitating careful handling and assessment of its safety profile.
