Methanesulfonamide Chemical Properties,Usage,Production

Chemical Properties

White to yellow crystals, powder or flakes

Uses

Methanesulfonamide will react with thionyl chloride, cyanates, carbon disulfide and ketones and aldehydes to prepare pharmaceuticals, brightening agent and other target molecules. It is also used in biological studies to predict binding affinity and binding mode of protein ligand complexes.

Uses

Methanesulfonamide is used in the synthesis of important organic reagents such as N-(2-methylthio-1-p-toluenesufonyl)methanesulfonamide and tert-butyl ((2-(trimethylsilyl)ethyl)sulfonyl)carbamate.
It can be used as a source of nitrogen in the conversion of carboxylic acids to corresponding nitriles.
It is widely used as a reagent in the synthesis of medicinally important compounds such as derivatives of indole-N-acetamide, methanesulfonamide pyrimidine-substituted 3,5-dihydroxy-6-heptenoates and repertaxin.
