Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its isocyanate group readily reacts with amines and alcohols, making it valuable for constructing ureas and carbamates in drug development. Commonly employed in the preparation of specialty polymers and pesticides due to its ability to introduce aromatic and ester functionalities in a single step. Also utilized in the production of dyes and photoactive compounds where the phenyl core with electron-withdrawing ester enhances stability and reactivity.
