Used primarily as a chemical intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a precursor in the production of certain fungicides and plant growth regulators due to its ability to form biologically active derivatives. Also employed in the synthesis of heterocyclic compounds, leveraging its thione functionality for coordination with metals or participation in cycloaddition reactions. Its reactivity makes it valuable in developing new sulfur-containing molecules for research and industrial applications.
