应用
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. 备注
