Used in the synthesis of agrochemicals and pharmaceuticals, particularly as an intermediate in the development of herbicides and insecticides. Its reactive isocyanate group enables it to form urea and carbamate derivatives, which are key structural motifs in crop protection agents. Also employed in the preparation of specialty polymers and functional materials where controlled reactivity and molecular design are required. The bromo and ethyl substituents allow for further functionalization via cross-coupling reactions, making it valuable in multi-step organic synthesis for building complex molecules.
