Used primarily as a reactive intermediate in organic synthesis, this compound serves as a sulfonylating agent to introduce the propenylsulfonyl group into various substrates. It is particularly useful in the preparation of sulfonate esters and sulfonamides, which are key motifs in pharmaceuticals and agrochemicals. Due to the presence of the vinyl-like double bond, it also enables further functionalization through addition or polymerization reactions. Its reactivity makes it valuable in the development of specialty monomers, cross-linking agents, and in the synthesis of bioactive molecules where sulfonyl chloride functionality is required.
