Application

4-Bromo-2,5-dichloropyridine serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and specialty chemicals. It is widely used in palladium-catalyzed cross-coupling reactions to construct biaryl systems for drug discovery. Researchers also employ it in the development of herbicides and fungicides due to its reactive halogen sites. Its pyridine core is valuable in material science for creating nitrogen-containing heterocycles with tailored electronic properties.
