One of the mysteries of the English language finally explained.
A synthetic compound with antibacterial properties which is the basis of the sulphonamide drugs.
Alternative name: p-aminobenzenesulphonamide; chemical formula: (H₂N)C₆H₄(SO₂NH₂)
- ‘Earlier this month, Japanese inspectors in Okinawa found excessive levels of sulfanilamide in a 600 kg batch of live eels imported from Taiwan.’
- ‘The colorimetric determination of the reaction was achieved by adding 1 ml of sulphanilamide and 1 ml of aqueous 10 mM N - 1-naphthyl-ethylene-diamine-dihydrochloride.’
- ‘The samples from the above were reacted with Greiss reagent (1% sulfanilamide, 2% H 3 PO 4 and 0.1% naphthylethylenediamine dihydrochloride).’
- ‘After 10 or 20 min of incubation at 26°C, the reaction was stopped by the addition of an equal volume of sulphanilamide.’
- ‘An early miss concerned the antibacterial properties of sulfanilamide, which were overlooked for more than 20 years, notably by chemists at I.G. Farbenindustrie who patented the recently synthesized compound in 1909.’
1930s: from sulphanilic (from sulphur + aniline + -ic)+ amide.
