General Description
2,4-dibromo-1-(2,4-dibromophenyl)benzene is a chemical compound with the molecular formula C12H6Br4. It is a type of brominated aromatic compound, which is commonly used as a flame retardant in various industrial products such as plastics, textiles, and electronics. 2,4-dibromo-1-(2,4-dibromophenyl)benzene is known for its high thermal stability and resistance to degradation, making it an effective additive for improving the fire resistance of materials. However, it is also considered to be a persistent organic pollutant and has been linked to concerns about its impact on human health and the environment. Given its potential risks, there is ongoing research and regulation regarding the use and disposal of 2,4-dibromo-1-(2,4-dibromophenyl)benzene in industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 66115-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,1 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66115-57:
(7*6)+(6*6)+(5*1)+(4*1)+(3*5)+(2*5)+(1*7)=119
119 % 10 = 9
So 66115-57-9 is a valid CAS Registry Number.

Catalytic asymmetric bromine-lithium exchange: A new tool to build axial chirality
Perron, Quentin,Alexakis, Alexandre
supporting information; experimental part, p. 2611 - 2620 (2011/01/05)
We present here the first catalytic desymmetrization of the 2,2′,6,6′-tetrabromobiphenyl 1 and analogues, by a bromine-lithium exchange catalyzed by either diamines or diether derivatives (0.5 equiv.), yielding axially chiral compounds in high yield (up to 89%) and high enantioselectivity (up to 82%).
