Used primarily as a reagent in organic synthesis, it serves as a key intermediate in the preparation of various sulfonamide derivatives. These derivatives are often employed in the development of pharmaceuticals, particularly in the synthesis of drugs with antibacterial or anti-inflammatory properties. Additionally, it is utilized in the modification of peptides and proteins, enabling the study of their structure and function. Its role in creating sulfonyl-containing compounds also extends to agrochemicals, where it contributes to the production of herbicides and pesticides. The compound’s reactivity with amines and alcohols makes it valuable in constructing complex molecules for research and industrial applications.
