Used as a versatile reagent in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It serves as a source of the dimethylaminomethylene group, enabling the formation of thioamides and other sulfur-containing derivatives. Commonly employed in the synthesis of agrochemicals, dyes, and bioactive molecules due to its ability to introduce functional diversity in molecular structures. Also utilized in the development of specialty materials where sulfur functionality enhances performance.
