Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active pharmaceutical ingredients (APIs). Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in creating complex molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build carbon-carbon bonds in drug discovery. Also utilized in the preparation of kinase inhibitors and other biologically active compounds due to the reactivity of the bromine atom and the electron-donating ethoxy group on the pyridine ring.
