Description
1-(2-Pyridylazo)-2-naphthol is widely used as an indicator for complexometry. It is used as a reagent for the extraction and spectrophotometric determination (for colorimetric analysis) of many transition metal elements like arsenic, chromium, cobalt, copper, cadmium, manganese, zinc and zirconium. It is also used for the analysis of uranium and thorium in solutions. 1-(2-Pyridylazo)-2-naphthol is also commonly used as an acid-base indicator. This reagent is slightly soluble in acidic solutions and soluble in alkaline solutions. The aqueous solution is yellow at pH12.
