Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 820959-17-9, Name is Ac-Beta-Ala-His-Ser-His-OH, SMILES is CC(NCCC(N[C@@H](CC1=CNC=N1)C(N[C@@H](CO)C(N[C@@H](CC2=CNC=N2)C(O)=O)=O)=O)=O)=O, belongs to imidazoles-derivatives compound. In a document, author is Otmacic, H, introduce the new discover, COA of Formula: C20H28N8O7.
Copper corrosion inhibitors in near neutral media
The efficiency of nontoxic imidazole derivatives as copper corrosion inhibitors in sodium chloride solutions was studied by electrochemical polarization methods (Tafel extrapolation and polarization resistance method) and weight-loss measurements. Results obtained during this study show that inhibitors with higher molecular weight, especially those with a phenyl ring, have better inhibiting properties. The values of free energy of adsorption, as calculated from Freundlich isotherm, indicate that investigated imidazole derivatives physisorbe on the copper surface. (C) 2002 Elsevier Science Ltd.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 820959-17-9 is helpful to your research. COA of Formula: C20H28N8O7.
