CAS 51169-05-2: 2(1H)-Pyridinone, hydrazone, monohydrochloride

2-Hydrazinylpyridine hydrochloride is a ligand that is used in complex formation. It has been shown to form ternary complexes with cobalt(II) ions and carbon monoxide. The formation constants are dependent on the pH of the reaction mixture and the temperature. 2-Hydrazinylpyridine hydrochloride forms a thermodynamically stable ternary complex with cobalt(II) ions and carbon monoxide, which is formed by equilibrium reactions. Optimization of parameters such as the concentration of cobalt(II) ions in the reaction mixture yields an optimized system that produces a potentiometric measurement for speciation.
