Used in organic synthesis as a building block for pharmaceuticals and bioactive compounds. Its isothiocyanate group readily reacts with nucleophiles like amines and thiols, making it valuable in the development of heterocyclic compounds with potential medicinal properties. Commonly employed in the design of kinase inhibitors and antimicrobial agents. Also utilized in chemical biology for labeling and cross-linking biomolecules due to its selective reactivity. Shows promise in the synthesis of fluorescent probes for cellular imaging.
