Dimethylglyoxime is a simple dioxime compound widely used as a highly selective analytical reagent. It appears as a white crystalline powder, insoluble in water but soluble in alcohol and ether. Its molecular structure features two oxime groups that form a stable, bright-red coordination complex specifically with nickel(II) ions. This property enables precise qualitative and quantitative analysis of nickel. DMG exhibits excellent thermal stability and low volatility. It is also employed in laboratory research for metal ion separation, as well as in electroplating baths as an additive to improve deposit quality and corrosion resistance.

Q1: What is Dimethylglyoxime (CAS 95-45-4) and how is it used in metal analysis?
A: Dimethylglyoxime (DMG) is an organic dioxime compound primarily utilized as a highly specific chelating agent in analytical chemistry and hydrometallurgy. When introduced to a solution containing metal ions under slightly ammoniacal conditions, DMG selectively targets nickel ions, forming a vivid, cherry-red insoluble coordination complex known as nickel dimethylglyoxime. This distinct reaction allows scientists and industrial plants to precisely quantify, precipitate, and separate nickel from other metals.
Q2: What precautions should I take when handling dimethylglyoxime?
A: Bulk Dimethylglyoxime is a stable crystalline powder but should be handled with standard industrial care. It should be stored in a cool, well-ventilated warehouse away from flame hazards and incompatible strong oxidizers. Workers should wear basic personal protective equipment (PPE), including dust masks and safety glasses, to prevent inhalation of airborne powder particles.
Q3: Where can I source dimethylglyoxime?
A: Our brand NovaBioX® DMG guarantees an analytical assay of ≥99.0% and superior solubility in alcohol. Contact our chemical export desk today to get an instant spot price quote or to request a free laboratory testing sample for your purification trials!
