  • Applications

    Diphenamid (CAS 957-51-7) is primarily encountered in agriculture as a selective herbicide used for weed control in cereals and other crops; in industry, it serves as an intermediate for the synthesis of other organic compounds, including ingredients for agrochemicals and specialty chemicals; in research and development, it is used as a reference compound for evaluating amide-type herbicides and related chemistries; at the same time it can function as a building block in preparing materials and formulations for agrochemical research, with use subject to local regulations and formulation limits.
