What is Sulfanilamide?

Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial. Chemically, it is an organic compound consisting of an aniline derivitized with a sulfonamide group. Powdered sulfanilamide was used by the Allies in WWII to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to previous wars. Modern antibiotics have supplanted sulfanilamide on the battlefield; however, sulfanilamide remains in use for treatment of vaginal yeast infections.

The term "sulfanilamides" is also used to describe a family of molecules containing these functional groups. Examples include:

  • Furosemide, a loop diuretic
  • Sulfadiazine, an antibiotic
  • Sulfamethoxazole, an antibiotic
