Used in the synthesis of pharmaceutical intermediates, particularly in the development of active pharmaceutical ingredients (APIs) for drugs targeting central nervous system disorders and anti-inflammatory agents. Its reactivity as an isocyanate allows it to form urea and carbamate derivatives, which are key structural motifs in medicinal chemistry. Commonly employed in cross-coupling reactions due to the presence of bromo and fluoro substituents, enabling further functionalization in complex molecule assembly. Also utilized in agrochemical research for building blocks in pesticide formulations. Requires careful handling due to high reactivity and potential toxicity.
