Application

2,3-Dichloropyridine serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and crop protection agents. Its dichloro-substituted pyridine core is leveraged in palladium-catalyzed cross-coupling reactions to construct biaryl systems. Researchers utilize it to develop ligands for catalysis and functional materials. In medicinal chemistry, it aids in creating kinase inhibitors and antimicrobial compounds. Also employed in electronic materials for its electron-withdrawing properties.
