Di Methyl Glyoxime – 500 gram 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 particularly important in inorganic qualitative analysis because it forms a characteristic scarlet-red precipitate with nickel(II) ions under suitable reaction conditions. This selective complex-forming behaviour makes Dimethylglyoxime useful in nickel identification, gravimetric analysis, coordination chemistry, and analytical method development. It is soluble in several organic solvents, including ethanol and acetone, while its solubility in water is limited. The reagent is used in school and college chemistry practicals, university laboratories, and research facilities where appropriate analytical methods require it. Lab Wale offers Di Methyl Glyoxime in 500 gram packs for suitable 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 rather than its 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 salts and metal complexes. Confirm the chemical identity and required grade before purchasing or preparing analytical reagent solutions.

How does Dimethylglyoxime identify nickel ions?

Under suitable reaction conditions, Dimethylglyoxime reacts with nickel(II) ions to form a characteristic scarlet-red, sparingly soluble nickel–dimethylglyoxime complex. This reaction is widely used in qualitative inorganic analysis and can 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. Avoid inhaling dust and prevent contact with the eyes and skin. Wear suitable protective gloves, laboratory 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 segregated from incompatible chemicals and follow the supplier’s 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 applicable 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. Use appropriate ventilation, clean spills using approved laboratory procedures, and dispose of residues through authorised chemical-waste channels in accordance with institutional requirements.
