5-amino-2-[(4-methylphenyl)amino]benzenesulfonic acid

Description:

5-Amino-2-[(4-methylphenyl)amino]benzenesulfonic acid, commonly referred to as a sulfonic acid derivative, is an organic compound characterized by the presence of both amino and sulfonic acid functional groups. It features a benzene ring substituted with an amino group and a sulfonic acid group, which contributes to its acidic properties. The presence of the 4-methylphenylamino group enhances its solubility in polar solvents and may influence its reactivity and interaction with other chemical species. This compound is typically a solid at room temperature and is known for its use in dye manufacturing, particularly in the production of azo dyes, due to its ability to form stable complexes with metal ions. Additionally, its sulfonic acid group imparts significant water solubility, making it useful in various applications, including as a reagent in biochemical assays. Safety data indicates that it should be handled with care, as it may pose health risks upon exposure.
