Lazaro, F. published the artcileStopped-flow injection determination of copper(II) at the ng ml-1 level, Application of 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Analytica Chimica Acta (1984), 177-85, database is CAplus.
A stopped-flow injection method for determination of Cu(II) in the range 0.2-300 ng/mL is proposed, based on the catalytic effect of this ion on the 2,2′-dipyridylketone hydrazone/H2O2 reaction. The oxidation product shows an intense blue fluorescence that is monitored at excitation wavelength = 350 nm, emission wavelength = 427 nm. The sampling rate (72/h), relative standard deviation (1.4%), and the lack of interference from most foreign ions allowed application of the method to the determination of Cu in foods and blood serum.
Analytica Chimica Acta published new progress about 2215-33-0. 2215-33-0 belongs to pyridine-derivatives, auxiliary class Pyridine,Amine, name is 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, and the molecular formula is C11H10N4, Application of 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine.
