Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to participate in cross-coupling reactions, enabling the formation of complex heterocyclic systems. Its sulphonamide linkage and brominated pyridine ring make it valuable for modifying biological activity in drug candidates. Also applied in research settings for designing compounds with enhanced binding affinity and selectivity toward specific enzyme targets.
