What is "dimethylglyoxime"

n. (context organic compound English) The oxime ''2,3-butanedione dioxime'' that is used as a reagent in the analysis of nickel and palladium

n. a compound used in analysis as a precipitant for palladium or nickel

Dimethylglyoxime is a chemical compound described by the formula CHC(NOH)C(NOH)CH. Its abbreviation is dmgH for neutral form, and dmgH for anionic form, where H stands for hydrogen. This colourless solid is the di oxime derivative of the diketone butane-2,3-dione (also known as diacetyl). DmgH is used in the analysis of palladium or nickel. Its coordination complexes are of theoretical interest as models for enzymes and as catalysts. Many related ligands can be prepared from other diketones, e.g. benzil.
