2,5-Dihydroxy-1,4-benzenedisulfonic acid

Description:
2,5-Dihydroxy-1,4-benzenedisulfonic acid, with the CAS number 4444-23-9, is an organic compound characterized by its structure, which features two hydroxyl groups and two sulfonic acid groups attached to a benzene ring. This compound is typically a white to light yellow crystalline solid, highly soluble in water due to the presence of the sulfonic acid groups, which enhance its ionic character. It exhibits strong acidity, making it useful in various chemical applications, including as a reagent in organic synthesis and as a potential intermediate in dye manufacturing. The presence of multiple functional groups allows for diverse reactivity, including potential interactions with metal ions and other organic compounds. Additionally, its dihydroxy and disulfonic functionalities contribute to its role as a chelating agent and in the formulation of certain types of surfactants. Safety data should be consulted for handling, as with many sulfonic acids, it may pose health risks if not managed properly.
