Used as a key intermediate in pharmaceutical synthesis, particularly in the production of nicotinic receptor agonists and antagonists. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to construct complex pyridine-containing molecules. Valued in agrochemical research for developing herbicides and pesticides due to its halogenated aromatic structure. Also utilized in material science for synthesizing functionalized ligands and catalysts. Its salt form enhances stability and solubility, making it suitable for solid-phase reactions and purification processes.
