Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its halogenated structure makes it valuable in building active ingredients that target specific weed species while minimizing impact on crops. Also employed in the development of pharmaceuticals where picolinic acid derivatives show biological activity. Commonly utilized in research for constructing complex heterocyclic compounds due to its reactive halogen sites, allowing for selective cross-coupling reactions in organic synthesis.
