Used primarily as an intermediate in organic synthesis, it plays a key role in the production of various pharmaceuticals and agrochemicals. Its sulfonyl chloride group is highly reactive, making it valuable for introducing sulfonamide functionalities into molecules, which are often found in drugs with antibacterial, antiviral, or anti-inflammatory properties. Additionally, it is employed in the development of specialty chemicals and dyes, where its structure contributes to the creation of complex organic compounds. Its applications also extend to research and development, particularly in the design of novel compounds with potential therapeutic or industrial uses.
