Application
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.

1-Nitroso-2-naphthol reacts with various 5-hydroxyindoles as well as para-substituted phenols and guaiacols. Consequently, this reaction has long been used to measure tyrosine in tyrosinosis and tyrosinemia, homovanillic acid in neuroblastoma, and 5-hydroxy-3-indoleacetic acid in the carcinoid tumor.
