1-(2-Pyridylazo)-2-naphthol (PAN), an orange colored dye, is commonly used as an acid-base indicator. It can form chelates with metal ions, which makes it a valuable indicator in complexometric titrations. PAN is also a spectrophotometric reagent, which can extract metal chelates into an organic solvent.
