Azo dye of quinoline named 5-(3-pyridylazo)-8-hydroxyquinoline (PAHQ) was prepared via coupling reaction diazonium salt 3-aminopyridine and 8-hydroxyquinoline. he PAHQ characterized by elemental analysis, mass spectroscopy 1H-NMR. The complexes were under 2:1 (L:M) mole ratio. infrared spectroscopy, UV-Vis, molar conductance, magnetic susceptibility. IR spectra data indicate that ligand is bid...

A new hexadentate, tripodal 8-hydroxyquinoline ligand (QH3) and its trivalent metal chelates (MQ, M=Al3+, Ga3+, In3+) with hemicage structures have been prepared and the electrochemical and photophysical properties systematically studied. The hemicage structure of the metal complexes was characterized by 1H NMR, indicating a pure facial geometry, in contrast to their uncaged cousins with 8-hydr...

This report validates a technique of separating and labeling canine platelets using indium-1 1 llabeled 8-hydroxyquinoline (Yn-8-HQ). Platelet survival time in six normal dogs was 6.3 ? 0.7 (SD) days. Labeling effisiency using this technique was 51.8 + 9.2% (SEM) and elution loss of 11LIn-8-HQ label from platelets was consistently less than 4%. Vn label offers no observable advantages over the ...

A series of manganese(I) tricarbonyl complexes formulated as [Mn(8-HQ)(CO)3Imd] (HQ = hydroxyquinoline and Imd imidazole derivatives) was synthesized fully characterized. These structures could be easily accessed from a common dimeric edifice [Mn2(8-HQ)2(CO)6]. The structure this complex has been confirmed by X-ray diffraction studies. Its reaction with range derivatives (Imd) yielded the monom...

in order to study the physiological effects of some of the essential oils in comparison with 8-hydroxyquinoline in cut lisianthus flowers (eustoma grandiflorum l.), an experimental was conducted in a completely randomized design with three replications. traetments included 8-hydroxyquinoline, essential oil of australian cheesewood (pittosporum undudatum) and rosmary oil(rosmarinus officinalis) ...
