Key Advantages of Our Methanesulfonic Anhydride
Superior Sulfonylation Power
Methanesulfonic anhydride is a highly effective sulfonating reagent, offering greater reactivity than sulfonyl chlorides in many organic synthesis applications. It's your go-to for reliably generating mesylates and enhancing reaction yields.
Facilitates Complex Synthesis Pathways
Utilize this versatile chemical intermediate for esterification of alcohols and the formation of sulfonamides. Its ability to react with various substrates makes it invaluable for custom synthesis projects and pharmaceutical intermediate production.
Reliable Performance in Oxidation Reactions
When combined with DMSO, Methanesulfonic Anhydride forms a sulfoxonium complex, acting as a potent oxidizing agent for alcohols. This offers an alternative route for aldehyde and ketone synthesis, crucial for fine chemical manufacturing.
Broad Applications in Chemical Manufacturing
Mesylate Synthesis
Methanesulfonic anhydride is the reagent of choice for producing methanesulfonyl esters (mesylates), vital intermediates in pharmaceuticals and agrochemicals.
Aromatic Alkylation
Employ this anhydride in Friedel-Crafts reactions for methylsulfonation of aromatic rings, enabling the synthesis of valuable substituted compounds.
Amine Sulfonamidation
It efficiently converts amines into sulfonamides, a common functional group in drug discovery and material science.
Oxidation of Alcohols
As part of an oxidation system with DMSO, it transforms primary and secondary alcohols into carbonyl compounds, supporting diverse synthetic strategies.
