Grases, F. published the artcileA simple monitored thermometric determination of copper(II) by reaction-rate measurement based on the catalysis of the aerial oxidation of 2,2′-dipyridylketone hydrazone, SDS of cas: 2215-33-0, the publication is Analytica Chimica Acta (1984), 158(2), 389-93, database is CAplus.
The initial rate of oxidation of 2,2′-dipyridylketone hydrazone was measured by monitoring the rate of increase of temperature of the solution with a thermistor. Cu 0.2-2 mg/L was determined in the final solution with 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.
