Used primarily as a specialty intermediate in organic synthesis, this compound is valued for its alkyne and sulfone functionalities, which enable participation in coupling reactions and carbon-chain elongation processes. Its structure supports the development of complex molecules in pharmaceutical and agrochemical research. The methylsulfonyl group enhances polarity and can act as a directing or activating group in reaction pathways. Due to its reactivity, it is employed in the preparation of functionalized building blocks for advanced synthetic applications, particularly in the design of bioactive compounds. Handling requires caution due to potential instability associated with terminal alkynes.
