This compound is a crucial pyridine heterocyclic intermediate with Boc protected amino and bromo substituents on pyridine ring. It is widely used in pharmaceutical intermediate synthesis and organic chemistry research.

It can participate in Suzuki coupling, Heck reaction and Buchwald-Hartwig amination reactions to construct various substituted pyridine derivatives. It is commonly applied in the research and development of anti-cancer drugs, anti-inflammatory agents and central nervous system medicines. The Boc protecting group can be easily removed under acidic conditions to expose free amino group, which is convenient for further molecular modification and structural optimization. It is also widely used in compound library synthesis and structure-activity relationship study in medicinal chemistry.
