Ethoxycarbonyl isocyanate is widely used in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. It serves as a key reagent in the formation of carbamates and ureas, which are essential structures in many active ingredients. In pharmaceutical research, it is employed to modify or functionalize molecules, enhancing their biological activity or stability. Additionally, it is utilized in the development of polymers and coatings, where it acts as a cross-linking agent to improve material properties. Its reactivity with amines and alcohols makes it a versatile intermediate in organic synthesis.
