Abstract
2-(5-Bromo-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol (5-Br-PAPS) is one of the most useful spectrophotometric reagents for transition metals in pyridylazo compounds. In connection with the HPLC of metal complexes, 5-Br-PAPS is also excellent as a chelating agent owing to the sensitivity and thermodynamic stability of its complexes of metals, such as V, Cr, Fe, Co, Ni, and Cu.
