Dimethyl-bis-<1,1,2-trifluor-2-brom-ethyl>-zinn, also known as dimethylbis(1,1,2-trifluoro-2-bromoethane)zinc, is a chemical compound with the formula [(CH3)2Zn(CF2BrCF3)]2. It is a colorless, crystalline solid that is soluble in organic solvents. This organozinc compound is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. The compound is synthesized by reacting dimethylzinc with 1,1,2-trifluoro-2-bromoethane. It is sensitive to air and moisture, and should be handled under an inert atmosphere. Due to its reactivity and potential toxicity, it is important to follow proper safety precautions when working with this chemical.

662-82-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 662-82-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.Calculate Digit Verification of CAS Registry Number 662-82:
(5*6)+(4*6)+(3*2)+(2*8)+(1*2)=78
78 % 10 = 8
So 662-82-8 is a valid CAS Registry Number.
