This chemical is primarily used as a reagent in organic synthesis, particularly in the preparation of sulfonamides. It is valuable in the pharmaceutical industry for the development of various drugs, as it facilitates the introduction of sulfonyl groups into organic molecules. Additionally, it finds application in the synthesis of biologically active compounds, where the sulfonyl chloride moiety acts as a key functional group for further chemical modifications. Its role in creating complex molecular structures makes it a useful tool in medicinal chemistry and drug discovery processes.
