Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for targeted cancer therapies. Its halogen substitution pattern allows for selective cross-coupling reactions, enabling precise construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the distinct reactivity of bromo, fluoro, and iodo groups. Also utilized in the preparation of antiviral agents and agrochemicals where fluorinated pyridine scaffolds enhance metabolic stability and bioavailability.
