Cas no 856834-95-2 (3-Bromo-2-chloro-5-nitro-6-picoline)

3-Bromo-2-chloro-5-nitro-6-picoline is a halogenated and nitrated pyridine derivative, serving as a versatile intermediate in organic synthesis. Its distinct substitution pattern—bromo, chloro, and nitro groups at the 3, 2, and 5 positions, respectively, along with a methyl group at the 6 position—enables selective functionalization, making it valuable for pharmaceutical and agrochemical applications. The electron-withdrawing nitro group enhances reactivity in nucleophilic aromatic substitution, while the halogen substituents facilitate cross-coupling reactions. This compound’s structural features support its use in constructing complex heterocyclic frameworks, offering synthetic flexibility for researchers. High purity and stability further ensure reliable performance in demanding chemical processes.
