Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and plant growth regulators. Its reactivity allows for the introduction of the 4-chloropicolinoyl group into larger molecules, enhancing their biological activity. Commonly employed in coupling reactions to form amides and esters in fine chemical manufacturing. Also utilized in research settings for developing new bioactive compounds due to its ability to modify molecular structure with chlorine and pyridine functionalities.
