Used primarily as a reagent in organic synthesis, it facilitates the formation of thioesters and thioamides, which are crucial in peptide and protein chemistry. It also serves as a key intermediate in the production of pharmaceuticals, particularly those involving sulfur-containing compounds. Additionally, it finds application in the development of agrochemicals, aiding in the synthesis of pesticides and herbicides. Its role in material science includes the modification of polymers to enhance their properties, such as thermal stability and mechanical strength.
