2,7-Naphthalenedisulfonic acid

Description:
2,7-Naphthalenedisulfonic acid, with the CAS number 92-41-1, is an organic compound characterized by the presence of two sulfonic acid groups (-SO3H) attached to a naphthalene ring at the 2 and 7 positions. This compound is typically a white to light yellow crystalline solid that is soluble in water, which is a notable feature due to the presence of the sulfonic acid groups that enhance its polarity. It is commonly used as a dye intermediate and in the synthesis of various organic compounds. The sulfonic acid groups impart strong acidic properties, making it a useful reagent in various chemical reactions. Additionally, 2,7-naphthalenedisulfonic acid can act as a dispersing agent in dye formulations and has applications in the textile industry. Its structure allows for potential interactions with other molecules, making it valuable in research and industrial applications. Safety precautions should be taken when handling this compound, as with many sulfonic acids, due to its corrosive nature.
