Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogen substituents allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex pyridine-based structures. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce the pyridine core into drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-deficient aromatic ring and reactivity profile.
