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

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.
