Used primarily as an alkylating agent in organic synthesis, this compound is valued for its ability to introduce methylsulfonyl groups into target molecules. It serves as a bifunctional linker in the development of pharmaceutical intermediates, especially in the construction of sulfone-containing bioactive compounds. Its reactivity allows for the formation of carbon-sulfur bonds under mild conditions, making it useful in the synthesis of specialty chemicals and potential drug candidates. Additionally, it has been explored in the design of covalent inhibitors due to its selective alkylation properties.
