3-Chlorophenyl isocyanate is widely 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, fungicides, and insecticides, contributing to crop protection and pest management. In the pharmaceutical industry, it is utilized to create active pharmaceutical ingredients (APIs) for drugs targeting conditions such as inflammation, infections, and central nervous system disorders. Additionally, it is employed in the development of polyurethane foams and coatings, where it acts as a reactive component to enhance material properties like durability and chemical resistance. Its versatility also extends to research and development, where it is used in organic synthesis to explore new chemical pathways and compounds.
