  • Applications

    Sulprofos (CAS 35400-43-2) is primarily used as an organophosphate insecticide in agriculture to control pests on a wide range of crops. Typical uses include foliar sprays or soil applications in crop protection programs, and it is commonly formulated into pesticide products in common formulations such as emulsifiable concentrates or granules; it may also be used as an active ingredient in other pesticide formulations. In industrial contexts, sulprofos can serve as an intermediate in the synthesis of other organophosphorus compounds. Its use is subject to local regulations and formulation limits.
