This chemical is primarily utilized as a reagent in organic synthesis, particularly in the formation of sulfonate esters and sulfonamides. It is effective in facilitating the sulfonylation of various organic compounds, including alcohols and amines, due to its strong sulfonylating properties. Additionally, it is employed in the preparation of complex molecules in pharmaceutical research, where precise sulfonylation is required. Its stability and reactivity make it a valuable tool in the development of drug intermediates and fine chemicals.
