Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1127-45-3, is researched, Molecular C9H7NO2, about Determination and comparison of the stability constants of some metal complexes of 8-hydroxyquinoline N-oxide and 8-hydroxyquinoline, the main research direction is stability constant metal complex; lanthanous complex; oxine complex.Recommanded Product: 1127-45-3.

The stability constant of 8-hydroxyquinoline 1-oxide (or “”oxine N-oxide””) complexes with MnII, FeII, CoII, NiII, CuII, ZnII, CdII, UO2II, AlIII, FeIII, YIII, LaIII, CeIII, PrIII, NdIII, SmIII, GdIII, DyIII, HoIII, ErIII, TmIII, YbIII, and LuIII, and oxine complexes with LnIII and YIII were determined by using pH-metric titrations in 50 volume % aqueous dioxane in the presence of 0.30M NaClO4 as the constant ionic medium. With both the ligands, the “”Gd break”” is observed in the case of the lanthanon (Ln) complexes, whereas the bivalent ion complexes follow the Irving-Williams order of stability constant in the case of the oxine complexes. The stability constant of the oxine complexes were larger than those of the N-oxide complexes, though the oxine anion is only 5 times as basic as the N-oxide anion. A possible explanation for the increased stability of the oxine complexes in comparison with the corresponding N-oxide derivative is proposed.
