Used primarily as an intermediate in the synthesis of herbicides, particularly in the production of selective chlorinated picolinic acid-based weed control agents. It plays a key role in agricultural chemistry for developing plant growth regulators and post-emergence herbicides effective against broadleaf weeds. Its derivatives are valued for high potency at low application rates and stability in various formulations. Also investigated for use in specialty agrochemicals due to its reactivity and ability to form salts and esters with enhanced soil mobility and crop selectivity.
