General description

5,7-Dimethyl-8-quinolinol (Me2-quoH) is a specific non-extracting reagent for lanthanide ions at pH below 11. It is useful for the extraction of Al3+ metal ions and the transition metal ions at ordinary pH conditions.

Application

5,7-Dimethyl-8-quinolinol has been used in the preparation of the following:
  • tetrakis(5,7-dimethylquinolin-8-olato-κ2N,O)zirconium(IV) dimethylformamide disolvate
  • tetrakis (5, 7-dimethylquinolin-8-olato-κ2N,O) hafnium (IV) dimethylformamide disolvate
  • [Ru(Me2-quo)(dcbpy)2]+Cl- (dcbpy = 2,2′-bipyridinyl-4,4′-dicarboxyl acid; Me2-quo = 5,7-dimethyl-8-hydroxyquinolinate)
  • bis(5,7-dimethyl-8-hydroxyquinolinato)platinum(II) complex
