8-hydroxyquinoline
oxine

The roots of the invasive plant Centaurea diffusa release 8-hydroxyquinoline, which has a negative effect on plants that have not co-evolved with it.

Thus, 8-hydroxyquinoline is potentially useful to control American plants that have become invasive weeds in the Diffuse Knapweed's native range.

Its principal use is as a precursor to 8-hydroxyquinoline, which is a versatile chelating agent and precursor to pesticides.

SDB-005 is the indazole core analogue of PB-22 where the 8-hydroxyquinoline has also been replaced with a naphthalene group.

The wild-type and mutant strains showed the same pattern of inhibition by cycloheximide, 8-hydroxyquinoline, and benomyl.

Key words: tris(8-hydroxyquinoline)aluminum, Alq3, ab initio, assignments, infrared, Raman, thin films.

Key words: 8-hydroxyquinoline, silica gel, induction heating electrothermal vaporization, inductively coupled plasma atomic emission spectroscopy.

It is based on the precipitation of Sr with 8-hydroxyquinoline at pH 11.3 and counting of β particles with energy above 150 keV.

One letter from local farmers described how a nearby factory making 8-hydroxyquinoline, used as a deodorant and antiseptic, emitted noxious fumes that “make our days and nights impassable.”

The reaction of 8-hydroxyquinoline with aluminium(III) results in Alq3, a common component of organic light-emitting diodes (OLED's).

The sorbent XAD-OXINE was prepared by covalently binding 8-hydroxyquinoline onto the surface of the macroporous copolymer Amberlite XAD-2 to give about 20% surface coverage.

The adduct is formed by reaction of the aquo tris chelate in molten 8-hydroxyquinoline and the anyhdrous tris chelate is obtained by thermal decomposition of the adduct.

GOGAT activity was unaffected by ATP, ADP, 8-hydroxyquinoline, and 1,10-phenanthroline but was inhibited by EDTA, citrate, and parachloromercuribenzoate.

A comparison of the relaxation time data of 1-nitro-naphthalene with that of 8-hydroxyquinoline in a number of solvents indicates that a strong specific interaction occurs between the latter solute and the solvent 1,4-dioxan which leads to the formation of a complex.

It has a molecular weight of about 48 000 and is inhibited by 10−7 M p-hydroxymercury benzoic acid. It is not inhibited by the metal chelators EDTA, o-phenanthroline, and 8-hydroxyquinoline, or by diisopropyl phosphorofluoridate.

A 0.2% solution of 8-hydroxyquinoline in isopropanol sprayed on the skin and illuminated with shortwave ultraviolet (UV) light after several minutes reveals a pattern and type of metal based on trace amounts of metal transferred to the skin that are invisible under normal lighting.

Some of their properties, however, are entirely different, e.g. AlP1 reacts with 8-hydroxyquinoline about 250 times faster with a much lower energy of activation than does AlP2, is much less resistant to attack by HCl, and is precipitated at a pH about 0.5 pH units lower than AlP2.
