설명

일반 설명

Methanesulfonic anhydride is an organic compound that is commonly used as a reagent for the preparation of methyl sulfonates (mesylates). It is also used in the synthesis of methanesulfonamides using various amine precursors. Additionally, the mixture of methanesulfonic anhydride and dimethyl sulfoxide can be used as an oxidizing agent for the oxidation of primary and secondary alcohols to aldehydes and ketones.

애플리케이션

Methanesulfonic anhydride can be used as an amine base to synthesize glycosyl mesylates in situ from the corresponding free hemiacetals under mild conditions.
