5-Bromo-2-chloro-4-iodopyridine(CAT: L042233) is a halogenated heteroaromatic compound with the molecular formula C₅HBrClIN. It appears as a light-colored crystalline solid and is sparingly soluble in water but soluble in various organic solvents. Featuring three distinct halogen substituents on the pyridine ring, it serves as a highly versatile intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Sonogashira, and Stille couplings. This reactivity makes it valuable for constructing complex heterocycles, pharmaceuticals, and agrochemical candidates. The multiple halogens also enable selective functionalization at different positions, offering synthetic flexibility for medicinal chemistry and material science research applications.
