Sulfanilic acid

Sulfanilic acid is a chemical compound used mainly in creating dyes, pharmaceuticals, and food preservatives. It consists of a benzene ring (a simple hexagon-shaped carbon structure) bonded to an amino group (-NH₂) and a sulfonic acid group (-SO₃H). These functional groups give the compound its reactivity and solubility properties. Sulfanilic acid is typically produced through chemical reactions involving sulfonation and nitration of benzene. It’s important in industrial processes and research, especially in the manufacture of azo dyes and in analytical testing, due to its ability to react with other chemicals selectively.
