Sulfanilic acid (4-aminobenzenesulfonic acid) is an organic compound with the formula H3NC6H4SO3. It is an off-white solid. It is a zwitterion, which explains its high melting point. It is a common building block in organic chemistry. See more Sulfanilic acid can be produced the sulfonation of aniline with concentrated sulfuric acid. This proceeds via phenylsulfamic acid; a zwitterion with a N-S bond. Eugen Bamberger originally proposed a … See more Reflecting its wide use, sulfanilic acid is found in the leachates of landfills. It is produced by reduction of some azo dyes. See more • Orthanilic acid • Metanilic acid • Sulfanilamide See more As the compound readily forms diazo compounds, it is used to make dyes and sulfa drugs.
