Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where the pyridine ring serves as a core structure. Its bromine substituent at the 4-position allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in medicinal chemistry for building complex molecules. Also employed in the production of agrochemicals and specialty chemicals requiring substituted pyridine derivatives. The methyl groups at the 2- and 5-positions enhance electron density on the pyridine ring, influencing reactivity and selectivity in synthetic pathways.
