Dimethylglyoxime(Cas 95-45-4) Usage

Reactions

Nickel cation reacts with dimethylglyoxime forms an insoluble red precipitate of nickel dimethylglyoxime. Ni2+ + 2C4H8N2O2 → Ni(C4H7N2O2)2↓(red precipitate) + 2H+Dimethylglyoxime reacts with ferrous sulphate and ammonium hydroxide forms a complex compound of iron and ammonium sulphate and water is formed. FeSO4 + 2NH4OH + 2C4H8N2O2 → Fe(C4H7N2O2)2 + (NH4)2SO4 + 2H2O

General Description

Dimethylglyoxime (DMG) is a complexing ligand. Dimethylglyoxime forms a number of mixed ligand complexes with N-acetylglycine with metals such as VO(IV), Ni(II), Zn(II), Pd(II), Cd(II) and Pb(II). It is a useful reagent for the spectrophotometric determination of Co(II), Fe(II), Ni(II), Pd(II) and Re(VII).

Safety Profile

Poison by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise it from EtOH (10mL/g) or aqueous EtOH. [Beilstein 1 III 3105.] TOXIC.
