Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its reactive isothiocyanate group enables coupling reactions with amines to form thiourea derivatives, which are important in the creation of bioactive molecules. Also employed in the preparation of fluorinated organic compounds where the presence of both fluorine and chlorine enhances metabolic stability and binding affinity in active ingredients. Commonly utilized in research settings for designing novel crop protection agents and in medicinal chemistry for building blocks in drug discovery.
