CAS 137-51-9

Aniline-2,4-disulfonic acid

Description:

Aniline-2,4-disulfonic acid, with the CAS number 137-51-9, is an aromatic sulfonic acid derivative of aniline. It features two sulfonic acid groups (-SO3H) attached to the aromatic ring at the 2 and 4 positions, which significantly enhances its solubility in water compared to its parent compound, aniline. This compound is typically a white to light yellow crystalline solid and is known for its strong acidic properties due to the presence of the sulfonic acid groups. Aniline-2,4-disulfonic acid is often used as a dye intermediate and in the synthesis of various organic compounds. Its sulfonic acid groups also make it a useful reagent in analytical chemistry, particularly in the determination of metal ions. Additionally, it can act as a pH indicator and is involved in various industrial applications, including the production of textiles and pigments. Safety precautions should be taken when handling this compound, as it can be harmful if ingested or inhaled, and may cause skin irritation.
