2-Chlorophenyl isocyanate is primarily used in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. It serves as a key intermediate in the formation of ureas and carbamates, which are essential in the development of active pharmaceutical ingredients (APIs). Additionally, it is employed in the manufacture of pesticides and herbicides, where it contributes to the creation of compounds that enhance crop protection. Its reactivity with amines and alcohols makes it valuable in organic synthesis, enabling the production of complex molecules with specific functional properties.
