Application

5,6-Dibromopyridine-3-carboxylic acid serves as a key intermediate in the synthesis of bioactive molecules, including kinase inhibitors and antimicrobial agents. Its dibrominated pyridine core facilitates Suzuki-Miyaura and Buchwald-Hartwig cross-coupling reactions for constructing complex heterocycles. Researchers also utilize it to develop metal-organic frameworks (MOFs) and luminescent materials due to its rigid, electron-deficient structure. In medicinal chemistry, it is employed to modify pharmacokinetic properties of lead compounds.
