| Applications | Azo dye manufacturing — sulfanilic acid salts are a classic diazo-component building block used throughout azo dye and pigment manufacturing |
This compound is the water-soluble sodium salt of sulfanilic acid (4-aminobenzenesulfonic acid), a compound whose diazotizable amine group has made it a foundational building block in azo dye chemistry since the earliest days of synthetic dye manufacturing.
This compound is manufactured into azo dyes and pigments via diazotization and coupling chemistry, and used more broadly as a biochemical research reagent.
