Mercury, methyl(phenylethynyl)-, also known as phenylmethylmercury or phenylmercury acetylene, is an organometallic compound with the chemical formula C8H7Hg. It is a derivative of mercury, where a mercury atom is bonded to a phenyl group and a methyl group through an ethynyl (acetylene) bridge. Mercury, methyl(phenylethynyl)- is of interest in the field of organometallic chemistry and has potential applications in various chemical processes. However, due to the toxicity of mercury and its compounds, it is essential to handle and dispose of this substance with extreme caution to minimize environmental and health risks.

4342-28-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4342-28-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,4 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4342-28:
(6*4)+(5*3)+(4*4)+(3*2)+(2*2)+(1*8)=73
73 % 10 = 3
So 4342-28-3 is a valid CAS Registry Number.

A strikingly fast route to methylmercury acetylides as a new opportunity for monomethylmercury detection

Lombardo, Marco,Vassura, Ivano,Fabbri, Daniele,Trombini, Claudio

, p. 588 - 593 (2005)

Methylmercury σ-complexation to 1-alkynes is exploited in a new practical and sensitive quantitation of monomethylmercury in water and in biological tissues; indeed, methylmercury halides are detected at the nanomolar level by 10-(3-trimethylsilyl-2-propynyl)-9-(10H)-acridinone, in dichloromethane and in the presence of Bu4NF·3H2O.

REACTIONS OF ORGANOMERCURY FULMINATES WITH ACETYLENE DERIVATIVES

Sarlo, Francesco De,Guarna, Antonio,Goti, Andrea,Brandi, Alberto

, p. 115 - 122 (2007/10/02)

Organomercury fulminates react with acetylene derivatives to give unstable 3-(organomercurio)isoxazoles, which isomerize to 2-cyanoenolates.These are hydrolyzed with hydrochloric acid to the corresponding enols and are cleaved by water at the double bond.With monosubstituted acetylenes, substitution at the free position by the organomercury residue is predominant.
