Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its reactive sulfonyl chloride group allows for easy attachment to other molecules, making it valuable in constructing sulfonamide derivatives. Commonly employed in the development of biologically active compounds, including potential drug candidates targeting inflammation and central nervous system disorders. Also utilized in the synthesis of specialty polymers and functional materials due to its ability to introduce cyclic ketone and sulfonate functionalities into larger structures.
