2-Amino-1,4-benzenedisulfonic acid

Description:

2-Amino-1,4-benzenedisulfonic acid, also known as 4-Amino-2,5-benzenedisulfonic acid, is an aromatic sulfonic acid characterized by the presence of two sulfonic acid groups (-SO3H) and an amino group (-NH2) attached to a benzene ring. This compound is typically a white to pale yellow crystalline solid that is soluble in water due to its ionic nature. It exhibits strong acidic properties, primarily due to the sulfonic acid groups, and can act as a weak base because of the amino group. 2-Amino-1,4-benzenedisulfonic acid is often used in the synthesis of dyes, pigments, and as a reagent in various chemical reactions, particularly in the field of analytical chemistry. Its ability to form complexes with metal ions makes it valuable in applications such as colorimetric analysis. Additionally, it is important to handle this compound with care, as it may pose health risks if ingested or inhaled, necessitating appropriate safety measures during use.
