IPC behaviour of some sulphonated naphthols and nitroso-naphthols

Fresenius' Zeitschrift für analytische Chemie, 1988
The ion-pair chromatographic behaviour of a naphthol and some sulpho-substituted naphthols and nitroso-naphthols is studied. Formation of the ion-pair compounds is done either by pre-extraction or during elution with long-chained quaternary alkyl- or alkylarylammonium salts.

4-Chloro-1-naphthol

Acta Crystallographica Section C Crystal Structure Communications, 2009
Molecules of the title compound, C(10)H(7)ClO, (I), are connected by a single strong O-H...O hydrogen bond into a simple C(2) chain, which runs parallel to the c axis and is additionally stabilized by intermolecular pi-pi stacking interactions. The significance of this study lies in the comparison drawn between the crystal structure of (I) and those of

Metabolism of 1-naphthol by tyrosinase

Biochemical Pharmacology, 1985
1-Naphthol was metabolized by the polyphenol oxidase, tyrosinase, primarily to 1,2-naphthoquinone and to small amounts of 1,4-naphthoquinone as well as to covalently bound products. The inhibition of covalent binding by ethylenediamine, which reacts specifically with 1,2-naphthoquinone but not 1,4-naphthoquinone, suggested that most of the covalent ...

Contact dermatitis from Naphthol AS

Contact Dermatitis, 1990
Naphthol AS, a coupling agent in cotton dyeing, caused allergic contact dermatitis in 5 patients, sensitized from wearing a special kind of shirt. Patch tests with Naphthol AS and pieces of shirt were positive in all 5 patients. Analysis of 1 of the shirts revealed the presence of Naphthol AS.

Fungal degradation of 1-naphthol

Canadian Journal of Microbiology, 1972
The biological degradation of 1-naphthol was studied during growth, with replacement cultures and cell extracts of the fungus Fusarium solani. Radioactivity of 1-naphthol-1-14C disappeared partially during growth, but it was completely dissipated by cell-extract activity.

Toxicity of Irradiated 1-Naphthol

Radiation Research, 1973
Irradiation of bacteria in the presence of 1-naphthol produces a radiosensitization. The magnitude of the response is dependent upon cell concentration and type, and requires an extended incubation...

Naphthol AS-Färberei

1930
Als nach der Erfindung der ersten substantiven Baumwollfarbstoffe die Azofarben ihren Siegeszug auch in der Baumwollfarberei hielten, wurden die Anforderungen hoher, die man in bezug auf Echtheit zu stellen hatte. Durch eine geeignete Auswahl der Azo- und Diazokomponente konnte man die Verbesserung einer Reihe von Echtheitseigenschaften, wie z.

[Simultaneous determination of 1-naphthol and 2-naphthol in water by spectrofluorimetry].

Guang pu xue yu guang pu fen xi = Guang pu, 2010
A simple and sensitive method for the simultaneous determination of trace amounts of 1-naphthol and 2-naphthol by fluorescence spectrofluorimetry was established based on the fact that the excitation and emission wavelengths are different between 1-naphthol and 2-naphthol.
