Application

5-Chloro-2-cyanopyridine serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for antiviral and antitumor agents. The compound’s reactive nitrile group enables conversion to amidines, tetrazoles, and carboxylic acid derivatives for drug discovery applications. In material science, it acts as a precursor for functionalized pyridine ligands in catalytic systems. The chlorine substituent facilitates further functionalization via metal-catalyzed cross-coupling reactions in medicinal chemistry workflows.
