Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for further functionalization, making it valuable in medicinal chemistry for creating compounds with targeted biological activity. Additionally, it serves as a building block in organic synthesis for constructing complex molecules, including agrochemicals and dyes. Its halogenated pyridine core is particularly useful in cross-coupling reactions, enabling the formation of carbon-carbon and carbon-heteroatom bonds in drug discovery and material science.
