Sodium Sulfanilate
Sodium Sulfanilate (CAS: 515-74-2) is the monosodium salt of sulfanilic acid, supplied as a white to pale yellow crystalline powder that dissolves readily in water.
The molecule combines a primary aromatic amine with a sulfonate group, giving a water-soluble diazotisable intermediate that is easy to handle in aqueous media.
• Dye intermediates: diazotised and coupled to build azo dyes, especially acid and direct dye ranges.
• Agrochemical use: applied in preparations that protect wheat and other cereals against rust.
• Optical brighteners: an intermediate in the synthesis of stilbene-based fluorescent whitening agents.
• Analytical chemistry: used as a reagent for nitrite determination and in sulfanilic acid buffer systems.
