Jimenez Plaza, J. published the artcile2-Pyridylaldehyde-2-pyridylhydrazone as an analytical reagent. V. Spectrophotometric determination of copper(II), Application of 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Boletin de la Sociedad Quimica del Peru (1980), 46(1), 94-102, database is CAplus.
2-Pyridylaldehyde-2-pyridylhydrazone reacts with Cu(II) in pH 5 buffer solution (HOAc-NaOAc) to form a 1:1 complex. The reaction can be used to determine Cu(II) by measuring the absorbance of the complex at 350-370 nm. Beer’s law is obeyed for 1-6.5 ppm Cu. Tolerance levels are given for 30 ions.
Boletin de la Sociedad Quimica del Peru 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.
