General description

Dimethylglyoxime(DMG) is a complexing ligand.[1] Dimethylglyoxime forms a number of mixed ligand complexes with N-acetylglycine and various metals such as VO(IV), Ni(II), Zn(II), Pd(II), Cd(II) and Pb(II).[2]

Application

Dimethylglyoxime (DMG) may be used as complexing agent for the quantification of metallic imprurities [cobalt(II) and nickel(II)] in brine (5.5mol/l aqueous solution of sodium chloride) by adsorptive stripping voltammetry.[1] It may be used in the preparation of nickel dimethylglyoxime, a dye complex used for the fabrication of dye-sensitized solar cells.[3]
Dimethylglyoxime may be used as a chelating agent[4] for determining nickel ion in complexes by gravimetric[5], titrimetric[4] or colorimetric analysis.
