21843-82-3 Usage
General Description
(4-chlorophenyl)mercury - acetic acid (1:1) is a chemical compound formed by the combination of (4-chlorophenyl)mercury and acetic acid in a 1:1 ratio. (4-chlorophenyl)mercury is an organomercury compound, which are known to be highly toxic to humans and the environment. It is used as a pesticide and fungicide, but its use has been restricted due to its toxicity. Acetic acid, on the other hand, is a simple carboxylic acid commonly found in vinegar and is generally recognized as safe for humans in small quantities. When combined in a 1:1 ratio, the chemical compound (4-chlorophenyl)mercury - acetic acid (1:1) is likely to exhibit toxic properties due to the presence of the organomercury compound. It is important to handle and dispose of this compound with caution to prevent harm to humans and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 21843-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,4 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21843-82:
(7*2)+(6*1)+(5*8)+(4*4)+(3*3)+(2*8)+(1*2)=103
103 % 10 = 3
So 21843-82-3 is a valid CAS Registry Number.

Nucleophilic cleavage of the Si-C bond in organotrifluorosilanes and diorganodifluorosilanes
Voronkov, M. G.,Chermov, N. F.,Perlova, E. M.

The Si-C bond in aryltrifluorosilanes, 4-XC6H4SiF3 (X = H, CH3, Cl, Br or NO2), is readily cleaved by mercury(II) salts HgY2 (Y = Cl, Br, I, CN or OCOCH3) or HgO to form organomercurials of the type 4-XC6H4HgY or (4-XC6H4)2Hg, respectively.Electron-donating substituent X facilitate the reaction, whereas electron-withdrawing substituents make it more difficult.Mercury(II) salts and mercury(II) oxide also cleave the Si-C bond in chloromethyltrifluorosilanes, F3Si(CH3-nCln) (n = 1-3) to produce the corresponding organic mercurials containing an Hg(CH3-nCln) group.The substitution of the fluorine atom in organotrifluorosilanes by an alkyl group hinders the bond cleavage between the silicon atom and the electronegative organic substituent.The reactions studied are believed to follow a nucleophilic mechanism involving asynchronous formation of a four-centered transition state with a pentacoordinate silicon atom.
