| | 1-Nitroso-2-naphthol Usage And Synthesis |
| Chemical Properties | brown powder | | Uses | Organic synthesis, prevention of gum formation
in gasoline, dye intermediate, analytical reagent. | | Uses | 1-Nitroso-2-naphthol as a complexing agent for the on-line preconcentration of cobalt with FI-FAAS. 1-Nitroso-2-naphthol is the chelating ion-exchanger in the synthesis of alumina adsorbents that are of acidic, basic and neutral nature. It is used for the removal and preconcentration of Pb(II), Cu(II), Cr(III) from waste, as well as drinking water. It is also used in the preconcentration of cobalt using C(18) microcolumn with flow injection that is coupled to a flame atomic absorption spectrometry (FI-FAAS) system. 1-Nitroso-2-naphthol is used in the preparation of 1-nitroso-2-naphthol-sodium nitrite reagent. | | Definition | ChEBI: 1-Nitroso-2-naphthol is a member of naphthols. | | Safety Profile | Moderately toxic by ingestion.Many nitroso compounds are carcinogens. Ignites whenheated to 124°C. Mutation data reported. When heated todecomposition it emits toxic fumes of NOx. | | Purification Methods | Crystallise the naphthol from pet ether (b 60-80o, 7.5mL/g).
