Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogenated pyridine structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of agrochemicals and functional materials due to its stability and reactivity in palladium-catalyzed reactions. Also utilized in research settings for labeling and derivatization processes.
