Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its halogenated structure allows for selective reactivity in coupling reactions, making it valuable in the development of active ingredients in crop protection products. It is also employed in the preparation of pharmaceuticals where picolinic acid derivatives exhibit biological activity. Commonly utilized in research settings for the construction of complex heterocyclic systems due to its functional group compatibility and stability under various reaction conditions.
