Description

Description générale

Hydroxy naphthol blue disodium salt is a chemical compound belonging to the class of azo dyes commonly used as a pH indicator.It exists as small blue crystals. Hydroxy naphthol blue is suitable for the quantification of metal leaching in metal affinity chromatography. It changes color at pH range 12-13 from blue to reddish pink, in the presence of calcium ions and to deep blue in the presence of disodium ethylenediaminetetraacetic acid (EDTA).
