75-81-0 Usage
General Description
1,2-Dibromo-1,1-dichloroethane is a chemical compound with the molecular formula C2H2Br2Cl2. It is a colorless liquid that is primarily used as an intermediate in the production of other chemicals, such as flame retardants, agricultural chemicals, and pharmaceuticals. 1,2-Dibromo-1,1-dichloroethane is also used as a solvent and as a fumigant to control pests. However, it is considered to be a hazardous substance, with potential health effects including skin and respiratory irritation, and it has been classified as a potential human carcinogen. Due to its toxic and environmental impacts, its use is now heavily regulated in many countries.
Check Digit Verification of cas no
The CAS Registry Mumber 75-81-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75-81:
(4*7)+(3*5)+(2*8)+(1*1)=60
60 % 10 = 0
So 75-81-0 is a valid CAS Registry Number.

Ground- and Excited-State Carboxylate Radical Chain Carriers. Radical Chain Substitution Reactions with Acyl Hypohalites
Skell, Philip S.,May, Donald D.
, p. 3999 - 4008 (2007/10/02)
Earlier work with aliphatic carboxylate radicals held no prospect that they could be used as hydrogen abstractors in substitution reactions.Contrary to this expectation, acetoxy, propionoxy, isobutyroxy, and pivaloxy are effective in this role.At low temperatures radical chain brominations of alkanes and haloalkanes occur in satisfactory yields when the acyl hypobromites, RCO2Br, are used; the selectivities are independent of the structure of R.Two distinctive hydrogen-abstracting RCO2. are involved in these chain reactions, either the ? or ?a electronic states; which electronic state is the chain carrier is determined in the step RCO2Br + X. -> RCO2. + XBr.These C? and C? radicals resemble tert-butoxy in their hydrogen-abstraction selectivities.The concordance of these results with a state-of-the-art calculation is discussed.
