What does dimethylmercury smell like?
Dimethylmercury belongs to a class of organic mercury compounds known as alkyl mercuries. It is used primarily in research. It is a colorless liquid described as having a weak, sweet odor.
Where can I buy methyl mercury?
Dietary sources. Because methylmercury is formed in aquatic systems, and because it is not readily eliminated from organisms, it is biomagnified in aquatic food chains from bacteria, to plankton, through macroinvertebrates, to herbivorous fish and to piscivorous (fish-eating) fish.
What is dimethyl mercury used for?
Since ancient times, mercury has been recognized as a toxic substance. Dimethylmercury, a volatile liquid organic mercury compound, is used by a small number of chemistry laboratories as a reference material in nuclear magnetic resonance spectroscopy.
How do I get dimethylmercury?
Later, Frankland discovered that it could be synthesized by treating sodium amalgam with methyl halides: Hg + 2 Na + 2 CH3I → Hg(CH3)2 + 2 NaI. It can also be obtained by alkylation of mercuric chloride with methyllithium: HgCl2 + 2 LiCH3 → Hg(CH3)2 + 2 LiCl.
Can dimethyl mercury go through gloves?
DO NOT use latex, PVC, butyl, or neoprene gloves. Highly toxic dimethylmercury penetrates these materials rapidly; o Gloves must be thoroughly inspected prior to each use.
Why is dimethyl mercury so toxic?
Why is dimethylmercury toxic? It is one of the most potent neurotoxins known. It readily crosses the blood-brain barrier, probably due to its formation of a methylmercury-cysteine complex. It causes ataxia (lack of coordination), sensory disturbance and changes in mental state.
Where can I find mercury at home?

Can you touch liquid mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
How much dimethylmercury is toxic?
approximately 400 mg
Dimethylmercury is lethal at doses of approximately 400 mg of Hg (equivalent to a few drops) or 5 mg/kg body weight (Gosselin et al.,1984; Nierenberg et al., 1998).
Can mercury be purchased?
Mercury is legal for sale and purchase within the United States, with very few restrictions. Export of mercury is limited to 1g per order and Luciteria Science cannot ship to countries under trade embargo or interdiction by the USA.
Is liquid mercury illegal to have?
California law restricts the level of mercury in some products (such as general purpose lights and packaging), and bans the sale of other mercury-containing products outright (such as mercury-containing thermometers, blood pressure cuffs, etc.).
