CAS: 63-74-1 | C6H8N2O2S | 172.202 g/mol Sulfonamide antibacterial Sulfanilamide is an antibacterial and used in the treatment of vaginal yeast infections. It is a competitive inhibitor of dihydropteroate synthestase to block the synthesis of folic acid. It serves as an intermediate for the preparation of 2,6-disubstituted anilines by electrophilic substitution followed by removal of the sulfonamide blocking group by desulfonation with sulfuric acid. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
