| Chemical Properties | yellow-greenish to yellow-brownish powder | | General Description | 2-nitroso-1-naphthol helps in the extraction of cobalt ion as it is used as a selective complexing agent. It is used in the separation and preconcentration of Th(IV), Ti(IV), Fe(III), Pb(II) and Cr(III) by solid phase extraction. | | Safety Profile | Moderately toxic by
ingestion. Many nitroso compounds are
carcinogens. Questionable carcinogen with
experimental tumorigenic data. When heated
to decomposition it emits toxic fumes of
NOx. See also NITROSO COMPOUNDS. | | Purification Methods | Purify the naphthol by recrystallisation from pet ether (b 60-80o) or by dissolving it in hot EtOH, followed by successive addition of small volumes of water (m 158o dec). It also crystallises from *C6H6 or H2O. Crystallisation from *C6H6/pet ether gives m (106-109 o, also 109.5o). It has max at 274.5 and 382nm (CHCl3). It complexes with metals.
