The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 8-Hydroxyquinoline 1-oxide(SMILESS: OC1=CC=CC2=CC=C[N+]([O-])=C12,cas:1127-45-3) is researched.Formula: C9H11Br. The article 《Azo compounds from 8-hydroxyguinoline N-oxide and its analogs as a new class of organic reagents》 in relation to this compound, is published in Org. Reagenty Anal. Khim., Tezisy Dokl. Vses. Konf., 4th. Let’s take a look at the latest research on this compound (cas:1127-45-3).
Reagents for photometric and extraction-photometric determination of Co, Cu, Ni, Pd, Ag, and other metals were prepared by coupling benzenediazonium or its derivatives and 8-quinolinol N-oxide (I) and its derivatives Cu2+ was determined by extraction of its complex with the coupling product of diazotized picramic acid and I into CHCl3 from a pH 6-7 solution and measuring the absorbance. The same reagent was used for determining Pd phtometrically at pH 0.5-8. The complexes of metals other than Cu were not extractable.
