Sulfonamides and Derivatives

Sulfonamides and Derivatives

Sulphonamides are compounds that contain a sulphonamide functional group (-SO₂NH₂), where a sulphur atom is bonded to an amino group. They were among the first synthetic antibiotics used in medicine, inhibiting folic acid synthesis in bacteria, which gives them antimicrobial properties. They are mainly used to treat bacterial infections, although their use has declined due to antimicrobial resistance. In addition to their use as antibiotics, sulphonamides also have applications in the treatment of diseases such as malaria and inflammatory bowel diseases. At CymitQuimica, we offer high-purity sulphonamides and their derivatives for research in microbiology and pharmaceutical development.
