Description:
1,5-Naphthalenedisulfonic acid, 3-[2-[4-[2-[4-[2-(6-amino-1-hydroxy-3-sulfo-2-naphthalenyl)diazenyl]-7-sulfo-1-naphthalenyl]diazenyl]-1-naphthalenyl]diazenyl]-, sodium salt (1:4), with CAS number 87440-96-8, is a complex organic compound characterized by its azo dye structure, which includes multiple naphthalene rings and sulfonic acid groups. This compound is typically used in dyeing processes, particularly in textiles, due to its vibrant color and ability to bind to various substrates. The presence of amino and hydroxy groups enhances its solubility in water, making it suitable for aqueous dyeing applications. Additionally, the sulfonic acid groups contribute to its ionic nature, which can influence its interaction with other chemical species and its overall stability in solution. As a sodium salt, it is more soluble in water compared to its acid form, facilitating its use in industrial applications. Safety data should be consulted for handling, as azo dyes can have varying toxicity profiles depending on their structure and the presence of specific functional groups.
