2,7-Naphthalenedisulfonic acid, sodium salt (1:2)

Description:
2,7-Naphthalenedisulfonic acid, sodium salt (1:2), with the CAS number 1655-35-2, is an organic compound characterized by its structure, which features a naphthalene backbone with two sulfonic acid groups (-SO3H) positioned at the 2 and 7 positions, and sodium ions balancing the negative charges of the sulfonate groups. This compound is typically a white to light yellow powder and is soluble in water, making it useful in various applications. It is often employed as a dye intermediate, in the synthesis of other organic compounds, and as a dispersing agent in various industrial processes. The presence of sulfonic acid groups imparts strong acidic properties, contributing to its reactivity and ability to form salts. Additionally, its aromatic structure provides stability and potential for further functionalization. Safety data should be consulted for handling, as with many chemical substances, it may pose health risks if not managed properly.
