Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It plays a key role in the production of certain herbicides and insecticides due to its reactivity with amines and alcohols, forming ureas and carbamates that are active ingredients in crop protection products. Also utilized in the development of specialty polymers and resins where enhanced chemical resistance and thermal stability are required. Its selective reactivity makes it valuable in fine chemical synthesis for introducing isocyanate functionality in multi-step reactions.
