2-[(4-Aminophenyl)amino]-5-nitrobenzenesulfonic acid

Description:
2-[(4-Aminophenyl)amino]-5-nitrobenzenesulfonic acid, commonly referred to as "4-Amino-5-nitro-2-aminobenzenesulfonic acid," is an organic compound characterized by its sulfonic acid functional group, which enhances its solubility in water. This compound features an amino group and a nitro group on a benzene ring, contributing to its reactivity and potential applications in dye chemistry and as an intermediate in organic synthesis. It is typically a solid at room temperature and may appear as a crystalline powder. The presence of both amino and nitro groups allows for various chemical reactions, including electrophilic substitution and coupling reactions, making it useful in the production of azo dyes. Additionally, its sulfonic acid group imparts acidic properties, which can influence its behavior in different pH environments. Safety precautions should be taken when handling this compound, as it may pose health risks if ingested or inhaled, and proper disposal methods should be followed to minimize environmental impact.
