2,6-Naphthalenedisulfonic acid, 3-hydroxy-, sodium salt (1:2)

Description:

2,6-Naphthalenedisulfonic acid, 3-hydroxy-, sodium salt (1:2), with CAS number 83949-45-5, is an organic compound characterized by its sulfonic acid functional groups and a hydroxyl group attached to a naphthalene ring system. This compound typically appears as a solid, often in a crystalline form, and is soluble in water due to the presence of the sodium salt, which enhances its ionic character. It is commonly used as a dye intermediate and in various applications within the textile and paper industries. The presence of multiple sulfonic acid groups contributes to its strong acidity and ability to form complexes with metal ions, making it useful in various chemical processes. Additionally, its structure allows for potential applications in pharmaceuticals and as a dispersing agent. Safety data should be consulted for handling, as with many sulfonic acids, it may pose health risks if ingested or if it comes into contact with skin.
