Sulfanilic acid (4-aminobenzene sulfonic acid ) is a colourless crystalline solid produced from sulfonation of aniline.[1]
It readily forms diazo compounds and is used to make dyes and sulpha drugs. [1]
Sulphanilic acid exists as a zwitterion, and has an unusually high melting point. It is used as a standard in Combustion Analysis.
