One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: catalyst-palladium, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 14220-64-5, Name is Bis(benzonitrile)palladium chloride, molecular formula is C14H10Cl2N2Pd
Synthesis, characterization, DNA binding and cleavage studies of mixed-ligand Cu(II) complexes of 2,6-bis(benzimidazol-2-yl)pyridine
Four novel copper(II) complexes of the composition [CuLX] where L = 2,6-bis(benzimidazole-2yl)pyridine, X = dipyridophenazine (L1), 1,10-phenanthroline (L2), hydroxyproline (L3) and 2,6-pyridine dicarboxylic acid (L4) were synthesized and characterized by using elemental analysis, FT-IR, UV-vis, ESI-MS, molar conductance and magnetic susceptibility measurements. The complexes [CuLL 1] (NO3)2 [1], [CuLL2](NO 3)2 [2], [CuLL3](NO3) [3] and [CuLL4] (NO4) [4] are stable at room temperature. In DMSO the complexes [1] and [2] are 1:2 electrolytes, [3] and [4] are 1:1 electrolytes. Based on elemental and spectral studies five coordinated geometry is assigned to all the four complexes. The interaction of four copper ion complexes with calf thymus DNA were carried out by UV-vis titrations, fluorescence spectroscopy, thermal melting and viscosity measurements .The binding constant (Kb) of the above four metal complexes were determined as 5.43¡Á 104 M, -1 2.56¡Á10 4 M-1, 1.21¡Á104 M-1 and 1.57¡Á 104 M-1 respectively. Quenching studies of the four complexes indicates that these complexes strongly bind to DNA, out of all complex 1 is binding more strongly. Viscosity measurements indicate the binding mode of complexes with CT DNA by intercalation through groove. Thermal melting studies also support intercalative binding. The nuclease activity of the above metal complexes shows that 1, 2 and 3 complexes cleave DNA through redox chemistry. Springer Science+Business Media, LLC 2012.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: catalyst-palladium, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14220-64-5, in my other articles.
