Used primarily as an intermediate in the synthesis of herbicides and other agrochemicals. It plays a key role in the production of selective chloroacetanilide herbicides, which are effective in controlling weeds in crops like corn and soybeans. Due to its high reactivity, it is also employed in organic synthesis for introducing trichlorobenzoyl groups in pharmaceutical and pesticide development. Its derivatives contribute to improved stability and bioactivity in final products. Handling requires caution due to its moisture sensitivity and potential for causing irritation.
