Grases, F. published the artcileSpectrofluorometric kinetic determination of copper based on the autoxidation of 2,2′-dipyridyl ketone azine or hydrazone or phenyl-2-pyridyl ketone hydrazone, SDS of cas: 2215-33-0, the publication is Analytica Chimica Acta (1981), 21-8, database is CAplus.
Kinetic methods for determination of ppm levels of Cu are based on its catalytic effect on the autoxidation of the hydrazone and the azine of 2,2′-dipyridyl ketone and the hydrazone of phenyl-2-pyridyl ketone. The reactions are followed by measuring the rate of appearance of fluorescence. The methods suffer very few interferences.
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, SDS of cas: 2215-33-0.
