英语百科

Sulfonamide 磺酰胺

(重定向自Sulphonamides)
The structure of the sulfonamide group
Estructura de la sulfonamida.

In chemistry, the sulfonamide functional group (also spelt sulphonamide) is -S(=O)2-NH2, a sulfonyl group connected to an amine group. Relatively speaking this group is unreactive. The amine center is no longer basic. The S-N bond is cleaved only with difficulty. Because of the rigidity of the functional group, sulfonamides are typically crystalline. For this reason, the formation of a sulfonamide is a classic method to convert an amine into a crystalline derivative which can be identified by its melting point. Many important drugs contain the sulfonamide group.
