Used primarily as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and insecticides. It plays a key role in the production of chlorpyrifos and related organophosphate compounds, which are effective in pest control for a variety of crops. Due to its chlorinated structure, it provides a reactive scaffold for further chemical modifications in agrochemical manufacturing. Also utilized in the development of pharmaceuticals and specialty chemicals where chlorinated heterocycles are required. Its reactivity allows for selective substitutions, making it valuable in multi-step organic synthesis.
