Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves in the preparation of sulfur-containing organic compounds, particularly in reactions where the chloro and methylthio groups act as reactive sites for further functionalization. Commonly employed in the development of herbicides and fungicides due to its ability to modify bioactive molecules. Also utilized in the production of dyes and specialty polymers where sulfur functionality enhances material properties. Its reactivity makes it valuable in cross-coupling reactions and heterocycle formation in research and industrial settings.
