Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its reactive isothiocyanate group enables conjugation in bioconjugation techniques for biochemical assays and labeling. Also employed in the preparation of chiral ligands and catalysts for asymmetric synthesis. Shows utility in research for probing enzyme active sites due to selective reactivity with nucleophilic amino acid residues.
