There is 1 mol of en per mol of HCL. A lab student analyzed her nickel-en complex for ethylenediamine, en, content. A 0.579 g sample of the synthesized Ni-en complex was dissolved in about 50 mL of water and titrated with 0.181 M HCl (aq). Endpoint required 38.02 mL of the HCl (aq). Distilled to constant boiling point just prior to use.? Material has further advantages for use in pressure. Ground Ni(DMG)2 or a mixture of Ni(DMG)2 and an inert solid was placed in the cell and pressure was applied to obtain a thin film of the material between the diamond anvils. Quantatitative determination of nickel in a compound by gravimetric analysis 1 answer below » A 10.00 ml sample of an unknown aqueous nickel (II) solution was treated and found to produce 0.0532 g of Ni(DMG)2(Molar mass=288.9155g/mol) precipitate. Nickel-dimethylglyoxime complex (abbreviated as Ni(II)(DMG)2) modified carbon paste and graphite electrodes were prepared by mixing Ni(II)(DMG)2 with graphite paste, and coating Ni(II)(DMG)2 to.

Dimethylglycine (DMG) is a derivative of the amino acidglycine with the structural formula (CH3)2NCH2COOH. It can be found in beans and liver. It can be formed from trimethylglycine upon the loss of one of its methyl groups. It is also a byproduct of the metabolism of choline. Opening dmg on old laptop download.

When DMG was first discovered, it was referred to as Vitamin B16, but, unlike true B vitamins, deficiency of DMG in the diet does not lead to any ill-effects and it is synthesized by the human body in the citric acid (or Krebs) cycle meaning it does not meet the definition of a vitamin.


Dimethylglycine has been suggested for use as an athletic performance enhancer, immunostimulant, and a treatment for autism, epilepsy, or mitochondrial disease.[2] There is no evidence that dimethylglycine is effective for treating mitochondrial disease.[3] Published studies on the subject have shown little to no difference between DMG treatment and placebo in autism spectrum disorders.[4][5]

Biological activity[edit]

Dimethylglycine has been found to act as an agonist of the glycine site of the NMDA receptor.[6]

This compound is commercially available as the free form amino acid, and as the hydrochloride salt [2491-06-7 ]. DMG may be prepared by the alkylation of glycine via the Eschweiler–Clarke reaction. In this reaction, glycine is treated with aqueous formaldehyde in formic acid that serves as both solvent and reductant. Hydrochloric acid is added thereafter to give the hydrochloride salt. The free amino acid may have been obtained by neutralization of the acid salt, which has been performed with silver oxide.[7]
