Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure, with bromo at position 2, fluoro at 3, and nitro at 4, allows for selective substitution reactions, making it valuable in constructing complex pyridine-based molecules. The nitro group serves as an electron-withdrawing activator, facilitating nucleophilic aromatic substitutions, particularly at the 2-position. The bromo and fluoro groups enable sequential functionalization, allowing the introduction of various substituents in drug discovery pathways. Commonly employed in the development of active ingredients for crop protection products and in medicinal chemistry for kinase inhibitors and other bioactive compounds.
