Used primarily as a reagent in organic synthesis, this chemical is valuable for introducing sulfonyl groups into molecules, facilitating the creation of sulfonamides and sulfonate esters. It is particularly useful in peptide chemistry for protecting amino groups during complex synthesis processes. Additionally, it serves as an intermediate in the production of pharmaceuticals and agrochemicals, where its reactivity with amines and alcohols is leveraged to build more complex structures. Its role in cross-coupling reactions also makes it a key component in the development of advanced materials and specialty chemicals.
