Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of the N-methylsulfonamide functional group, which can enhance metabolic stability and binding affinity in bioactive molecules. Commonly employed in the development of medicinal compounds where sulfonamide moieties are required for activity. Also utilized in research settings for the synthesis of novel heterocyclic compounds and functionalized polymers.
