Widely used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders and anti-infective agents. Its halogen substitution pattern allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex pyridine-based molecules. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance bioavailability and binding affinity in target compounds. Commonly utilized in Suzuki and Buchwald-Hartwig coupling reactions to introduce functionalized pyridine moieties in drug discovery programs.
