3,4-Dichlorobenzamide is primarily used as an intermediate in the synthesis of herbicides, particularly in the production of chloramben, a selective herbicide effective against broadleaf weeds and some grasses in crops like corn, soybeans, and vineyards. The derived herbicides play a key role in controlling unwanted vegetation by inhibiting plant growth processes. Due to its reactivity, it is also utilized in the development of other agrochemicals and specialty chemicals. These derivatives help improve crop yield by reducing competition from weeds. As a chemical intermediate, proper handling is required to address potential environmental persistence and toxicity risks associated with its use and derivatives.
