One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 838-88-0, Name is 4,4′-Methylenebis(2-methylaniline), formurla is C15H18N2.

A phthalazine-based two-in-one chromogenic receptor for detecting Co2+ and Cu2+ in an aqueous environment
A new multifunctional and highly selective chemosensor 1 for Co2+ and Cu2+ was designed and synthesized. 1 could simultaneously detect both Co2+ and Cu2+ by changing its color from pale yellow to pink and to orange in a near-perfect aqueous solution. The binding modes of 1 to Co2+ and Cu2+ were determined to be a 2 : 1 complexation stoichiometry through Job’s plot, ESI-mass spectrometry analysis and H-1 NMR titration. The detection limits (1.5 and 2.1 mu M) of 1 for Co2+ and Cu2+ were lower than the DEP guidelines (1.7 mu M for Co2+) and the WHO guidelines (31.5 mu M for Cu2+) for drinking water. The chemosensor 1 could be used to quantify Co2+ and Cu2+ in water samples. Moreover, 1 could be used as a practical, visible colorimetric test kit for both Co2+ and Cu2+. The sensing mechanisms of Co2+ and Cu2+ by 1 were supported by theoretical calculations.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 838-88-0 help many people in the next few years. Category: phthalazines.
