Di Methyl Glyoxime- 1 Kg Packs

Di Methyl Glyoxime, commonly known as Dimethylglyoxime (DMG), is an organic analytical reagent belonging to the dioxime class of compounds. It has the molecular formula C₄H₈N₂O₂ and a molecular weight of approximately 116.12 g/mol. This white crystalline compound is widely recognised for its ability to form a characteristic red precipitate with nickel(II) ions under suitable chemical conditions, making it an important reagent in qualitative inorganic analysis. Dimethylglyoxime is used in analytical chemistry practicals, metal-ion identification, coordination chemistry investigations, and selected procedures for nickel determination. It is soluble in several organic solvents, including ethanol and acetone, but has limited solubility in water. Its performance depends on the analytical method, solution conditions, and reagent specifications. Lab Wale offers Di Methyl Glyoxime in 1 kg packs for appropriate educational, analytical, and research laboratory applications.

Frequently Asked Questions About Di Methyl Glyoxime

What is Di Methyl Glyoxime used for in laboratories?

Dimethylglyoxime is primarily used as an analytical reagent for detecting and determining nickel(II) ions. It forms a characteristic red complex with nickel under suitable conditions. It is also used in inorganic chemistry practicals, gravimetric analysis, and coordination chemistry research involving metal–ligand interactions.

What is the molecular formula and molecular weight of Dimethylglyoxime?

Dimethylglyoxime has the molecular formula C₄H₈N₂O₂ and a molecular weight of approximately 116.12 g/mol. Its empirical formula is C₂H₄NO, representing the simplest whole-number ratio of its constituent atoms. These values apply to the neutral Dimethylglyoxime compound, not its sodium salts or metal complexes.

What is the CAS number of Di Methyl Glyoxime?

The CAS Registry Number for Dimethylglyoxime is 95-45-4. This identifier distinguishes the neutral compound from related substances, including its sodium salts and metal complexes. Confirm the chemical identity before purchasing or preparing analytical reagent solutions.

How does Dimethylglyoxime help identify nickel ions?

Under suitable reaction conditions, Dimethylglyoxime reacts with nickel(II) ions to form a characteristic red, sparingly soluble nickel–dimethylglyoxime complex. This reaction is widely used in qualitative analysis and can also support gravimetric nickel determination when performed using an appropriate validated procedure.

How should Di Methyl Glyoxime be stored and handled safely?

Store Dimethylglyoxime in a tightly closed container in a cool, dry, well-ventilated location away from ignition sources. Avoid inhaling dust and prevent contact with the eyes and skin. Wear suitable protective gloves, clothing, and eye protection. Follow the applicable Safety Data Sheet, laboratory spill procedures, and approved chemical-waste disposal requirements.

Storage Conditions for Di Methyl Glyoxime

Store Di Methyl Glyoxime in a tightly closed, compatible container in a cool, dry, well-ventilated area, protected from moisture and excessive heat. Keep it away from ignition sources and incompatible chemicals, and follow the supplier’s specified storage recommendations. Maintain clear labelling and restrict access to authorised laboratory personnel in accordance with institutional chemical-storage procedures.

Precautions for Handling Di Methyl Glyoxime

Review the current Safety Data Sheet before use. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and minimise dust generation during weighing or transfer. Avoid inhalation and contact with the eyes or skin. Keep the material away from heat, sparks, and open flames, and use appropriate ventilation. Collect spills safely and dispose of residues through approved chemical-waste procedures in accordance with institutional requirements.
