1-(3,4-Dichlorophenyl)urea is an organic chemical intermediate primarily used in the synthesis of herbicides and other agrochemicals. It acts as a key building block for phenylurea derivatives, such as diuron, which are effective herbicides that inhibit photosynthesis in target plants. This compound is also employed in pharmaceutical and fine chemical manufacturing. Due to its role in producing selective weed control agents, it contributes to agricultural productivity by enabling the development of products that target weeds while sparing crops. Handling requires appropriate safety measures to prevent exposure and environmental release.
