Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding in biological systems, making it valuable in drug discovery. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to build complex molecules for medicinal chemistry. Also utilized in the preparation of agrochemicals and functional materials due to its halogenated pyridine core, which enhances reactivity and molecular diversity.
