Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where pyridine derivatives are required. It serves as a building block in the preparation of more complex molecules due to the reactivity of the bromine atom, which allows for cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in research and development for agrochemicals and specialty chemicals, especially where substituted pyridines enhance biological activity. Its structure supports the creation of compounds with improved selectivity and potency in drug design.
