Isopropyl isocyanate is primarily used in the synthesis of various organic compounds, particularly in the production of agrochemicals and pharmaceuticals. It serves as a key intermediate in the manufacture of herbicides, insecticides, and fungicides, contributing to crop protection and pest management. In the pharmaceutical industry, it is employed in the creation of active pharmaceutical ingredients (APIs) and other therapeutic agents. Additionally, it is utilized in the preparation of specialty chemicals, including polymers and coatings, where it acts as a building block for more complex structures. Due to its reactivity, it is also used in research and development for creating novel compounds with specific properties. Proper handling and safety measures are essential due to its toxic and hazardous nature.
