Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals. Its isothiocyanate group readily reacts with amines and thiols, making it valuable in the preparation of heterocyclic compounds. Commonly employed in the development of bioactive molecules, including kinase inhibitors and anti-inflammatory agents. Also utilized in chemical biology for labeling and modifying biomolecules due to its selective reactivity. Serves as a building block in the synthesis of liquid crystals and functional materials.
