Description

Description générale

1,3-Dihydroxynaphthalene is a dye intermediate forming stable colors when applied with particular mordants and in mixtures with other oxidizing dyes. This specific reagent is intended for the quantitative colorimetric determination of alduronic acids, such as glucuronic acid from urine. The mutagenicity of ozonation derivatives of 1,3-dihydroxynaphthalene against several Salmonella typhimurium strains has been studied.

Application

1,3-Dihydroxynaphthalene is utilized in carbohydrate chromatography, sometimes in conjunction with resorcinol. It has been used incorporated into a thin-layer electrophoretic method for the analysis of biomass degradation products which contain comprising mono-, oligo- and polysaccharides, and their derivatives, in addition to phenolic compounds.

Notes préparatoires

1,3-Dihydroxynaphthalene is soluble in ethanol (50 mg/ml), with heat as needed, yielding a clear to slightly hazy, colorless to orange-brown solution. It is also soluble in water and ether.
