Sulfanilamide is a sulfonamide antibacterial, one of the earliest, now largely replaced by more powerful antibiotics. It also has some uses in analytical chemistry.
Sulfanilamide is a white solid, soluble in hot water and organic solvents.
Can be purchased online.
Sulfanilamide can be made from benzene through a series of stages, as seen here.
- Make antibiotic
Sulfanilamide is a strong antibacterial agent, though lab grade is not safe to consume.
As it is sensitive to light, it should be kept in amber bottles, in dark places.
Can be dumped down the drain or in the trash, in small quantities.
