Used as an intermediate in organic synthesis, particularly in the preparation of sulfone and sulfonate derivatives. It serves in the development of pharmaceuticals and agrochemicals due to its ability to introduce ethoxycarbonylsulfanyl groups. The compound is also employed in the synthesis of heterocyclic compounds, where it acts as a building block for more complex molecules. Its ester and sulfanyl functionalities make it valuable in multi-step reactions involving nucleophilic substitution or condensation processes.
