Sulfanilamide is a yellowish-white or white crystal or fine powder. It has a density of 1.08 g/cm 3 and a melting point of 164.5-166.5 °C. The pH of a 0.5% aqueous solution of Sulfanilamide is 5.8 to 6.1. It has a λ max of 255 and 312 nm. [5] Solubility: One gram of sulphanilamide dissolves in approximately 37 ml alcohol or in 5 ml acetone.
[5] This method can be applied in many aspects, including determining the nitrate/nitrite concentrations in sewage or other biological samples such as intracellular fluids, given that the sample is clear and colorless. In a similar protocol, the levels of sulfonamide in blood can be detected similarly with the same principles.
Sulfamethoxazole, a sulfanilamide, is a structural analog of para-aminobenzoic acid (PABA). They compete with PABA to bind to dihydropteroate synthetase and inhibit conversion of PABA and dihydropteroate diphosphate to dihydrofolic acid, or dihydrofolate.

Sulfanilic acid can be produced by sulfonation of aniline with concentrated sulfuric acid. [5] This proceeds via phenylsulfamic acid; a zwitterion with a N-S bond. Eugen Bamberger originally proposed a mechanism involving a series of intramolecular rearrangements, with phenylsulfamic acid forming orthanilic acid, which rearranged to sulfanilic acid on heating.

Dansyl chloride or 5-(dimethylamino)naphthalene-1-sulfonyl chloride is a reagent that reacts with primary amino groups in both aliphatic and aromatic amines to produce stable blue- or blue-green–fluorescent sulfonamide adducts. It can also be made to react with secondary amines.
