3-Bromo-2-iodopyridine（Cat No.:L015109）is a halogenated heteroaromatic compound featuring a pyridine ring substituted with a bromine atom at the 3-position and an iodine atom at the 2-position. This compound is a valuable intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Sonogashira, and Buchwald–Hartwig couplings. The presence of two different halogens allows for selective functionalization, enabling sequential transformations. Its electron-deficient pyridine ring and halogen substituents make it useful in pharmaceutical development, agrochemical synthesis, and heterocyclic compound construction, offering structural versatility and reactivity for advanced molecular design.
