Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with potential antiviral and anticancer properties. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions such as Suzuki and Buchwald-Hartwig aminations to introduce aryl or amino groups. Also utilized in agrochemical research for developing novel pesticides and herbicides due to its electron-deficient pyridine core, which enhances binding to biological targets. Preferred in late-stage functionalization due to the differential reactivity of bromo and chloro substituents, enabling stepwise derivatization.
