Used as a key reagent in organic synthesis, particularly for the preparation of fluorinated compounds. It is employed in the development of pharmaceuticals and agrochemicals due to its ability to introduce fluorinated phenyl groups into molecules, enhancing their biological activity and stability. Additionally, it serves as a building block in the synthesis of heterocyclic compounds, which are important in medicinal chemistry. Its isothiocyanate group allows for efficient coupling with amines, making it valuable in the creation of ureas and thioureas, which are useful in drug discovery and material science.
