Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its brominated pyridine groups enable selective cross-coupling reactions, facilitating the construction of complex bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its rigid disulfane scaffold and halogen substitution pattern. Also utilized in the development of covalent inhibitors where the disulfide bond can participate in redox interactions within biological systems.
