Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive isocyanate group readily forms urea and carbamate derivatives, making it valuable in constructing biologically active molecules. Commonly employed in the development of sulfonamide-based drugs, where the fluorinated aromatic ring enhances metabolic stability and binding affinity. Also utilized in the preparation of specialty polymers and as a derivatizing agent in analytical chemistry for detecting compounds containing hydroxyl or amino groups.
