2,4-Dibromo-5-nitropyridine（Cat No.:L017689）is a halogenated nitropyridine derivative featuring bromine atoms at the 2 and 4 positions and a nitro group at the 5 position of the pyridine ring. This highly electron-deficient heteroaromatic compound is a valuable intermediate in organic synthesis, especially for constructing complex molecules via cross-coupling reactions such as Suzuki, Stille, or Buchwald–Hartwig reactions. The nitro group further activates the ring toward nucleophilic aromatic substitution, allowing for selective functionalization. It is used in medicinal chemistry, agrochemical development, and heterocycle synthesis to generate bioactive and structurally diverse compounds.
