Properties. EC Number 209-805-3. Some scientist created 6 kg of the substance without much bodily effects until about 1 month after. But dimethylmercury beats them all hands down for toxicity. It evaporates very fast. Dimethylmercury ((CH3)2Hg) is an organomercury compound. [13], The toxicity of dimethylmercury was highlighted with the death of Karen Wetterhahn, a professor of chemistry at Dartmouth College, in 1997. A novel feature of this compound is its unreactivity towards water and the fact that it reacts with mineral acids at a significant rate only at elevated temperatures,[4][5] whereas the corresponding organocadmium and organozinc compounds hydrolyze rapidly. Die Fortschritte anderer Betroffener geben ein aufschlussreiches Bild über die Wirksamkeit ab. As with many methyl-organometallics, it is a methylating agent that can donate its methyl groups to an organic molecule; however, the development of less acutely toxic nucleophiles such as dimethylzinc and trimethylaluminium, and the subsequent introduction of Grignard reagents (organometallic halides), has essentially rendered this compound obsolete in organic chemistry. AKOS015916085. Several lethal cases of poisoning in chemists have been described (Hunter, 1955; Nierenberg et al., 1998). Are there any satellite currently orbit the moon.? EINECS 209-805-3.

The easiest reaction is with mercuric chloride and methyllithium, both of which are not very hard to get if you are skilled enough at finding it. Who are you trying to poison? It is a very strong toxin to the nervous system. The molecule adopts a linear structure with Hg-C bond lengths of 2.083 Å. [11] Methylmercury crosses the blood–brain barrier easily, probably owing to formation of a complex with cysteine. It is formed by treating sodium amalgam with methyl halides : Hg + 2 Na + 2 CH 3 I → Hg (CH 3) 2 + 2 NaI. Still have questions? Professor Wetterhahn specialized in heavy metal poisoning. It contains methyl and mercury ions. CHEBI:30786. The compound reacts with mercuric chloride to give the mixed chloro-methyl compound: Whereas dimethylmercury is a volatile liquid, methylmercury chloride is a crystalline solid.[6]. Dimethylmercury is under poison category. Mercury, dimethyl-DIMETHYL MERCURY. Is Uranus more known for its smoothness or roughness? Actually, Dimethylmercury was once thrown around as an idea to increase the thrust of rocket engines at the start. It has also been used to calibrate NMR instruments for detection of mercury, although diethylmercury and less toxic mercury salts are now preferred.

[11] The American Occupational Safety and Health Administration advises handling dimethylmercury with highly resistant laminated gloves with an additional pair of abrasion-resistant gloves worn over the laminate pair, and also recommends using a face shield and working in a fume hood. The symptomatology and toxicokinetics are identical to those seen after exposure to MeHg compounds. It can also be obtained by alkylation of mercuric chloride with methyllithium : HgCl 2 + 2 LiCH 3 → Hg (CH 3) 2 + 2 LiCl. PubChem Substance ID 24859713. [10][12], Dimethylmercury is metabolized after several days to methylmercury. $\begingroup$ I'm not sure rate of skin absorption is the problem. How is it that we've been sending stuff up into space for years and yet, there is still zero evidence of aliens? It is formed by treating sodium amalgam with methyl halides: It can also be obtained by alkylation of mercuric chloride with methyllithium: The molecule adopts a linear structure with Hg-C bond lengths of 2.083 Å.[3].

I mean, if you even touch it with a gloved hand you'll die in 6 months like the Dartmouth professor. UNII-C60TQU15XY. The compound was one of the earliest organometallics reported, reflecting its considerable stability. Beilstein/REAXYS Number 3600205 . It will depend on different country's policy for chemist to buy such item. The acute toxicity of the compound was demonstrated by the 1997 death of heavy metal chemist Karen Wetterhahn, who died 10 months after a single exposure of only a few drops permeated through her disposable latex gloves. C60TQU15XY. Don't forget your Silver Shield laminated gloves, specialized DuPont lab coat, and 8 inch face shield under a fume hood! Examples of organic mercury compounds are dimethylmercury, phenylmercuric acetate, and methylmercuric chloride. For one thing, I can't find skin absorption values for HgMe2 to make a comparison. [2] It has a slightly sweet odor, although inhaling enough of the chemical to notice this would be hazardous. The symptoms of poisoning may be delayed by months, resulting in cases in which a diagnosis is ultimately discovered, but only at the point in which it is too late for an effective treatment regimen to be successful.
