Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It plays a key role in the formation of sulfonamide derivatives, which are essential in developing drugs with antibacterial, antiviral, or anti-inflammatory properties. Additionally, it is utilized in the preparation of advanced materials, such as polymers and liquid crystals, due to its ability to introduce sulfonyl groups into molecular structures. Its reactivity makes it valuable in research and industrial applications for creating complex organic compounds.
