2-Aminophenol-4,6-disulfonic acid

Description:
2-Aminophenol-4,6-disulfonic acid, with the CAS number 120-98-9, is an organic compound characterized by the presence of both amino and sulfonic acid functional groups. It features a phenolic structure with two sulfonic acid groups located at the 4 and 6 positions, and an amino group at the 2 position of the benzene ring. This compound is typically a white to light yellow crystalline solid that is soluble in water due to its sulfonic acid groups, which enhance its hydrophilicity. It is commonly used in various applications, including as a dye intermediate, in the synthesis of pharmaceuticals, and in analytical chemistry as a reagent. The presence of the amino group allows for potential reactivity in further chemical transformations, while the sulfonic acid groups contribute to its acidity and ionic character. Safety considerations should be taken into account, as with many sulfonic acids, due to potential irritant properties.
