Used as a reagent in the synthesis of various organic compounds, particularly in the preparation of peptides and proteins for biochemical studies. It is often employed in the modification of amino acids and peptides to introduce functional groups that aid in labeling or cross-linking. Additionally, it serves as a key intermediate in the production of pharmaceuticals and agrochemicals, where its isothiocyanate group enables the formation of thiourea derivatives. Its applications also extend to material science, where it is utilized in the development of polymers and coatings with specific properties.
