Used as an intermediate in the synthesis of pesticides and herbicides, particularly in the production of thiocarbamate-based agrochemicals that inhibit weed growth by disrupting plant cell division. Also employed in the manufacture of rubber additives and vulcanization accelerators, enhancing the curing process and improving the elasticity and durability of rubber products. Additionally, it serves as a reagent in organic synthesis for introducing ethylthio groups in pharmaceutical and fine chemical manufacturing.
