558-57-6 Usage
Description
1,2-Dibromo-1,1-dichloro-2,2-dichloroethane, commonly referred to as DBDCD, is a highly toxic and environmentally persistent chemical compound. It is characterized by its ability to bioaccumulate and persist in the environment, posing significant risks to both human health and the ecosystem.
Uses
Used in Historical Pesticide and Fumigant Applications:
DBDCD was historically utilized as a pesticide and fumigant due to its effectiveness in controlling pests. However, its use has been largely discontinued in many parts of the world due to the recognition of its harmful effects on human health and the environment.
Used in Regulatory and Hazardous Waste Management:
Given its classification as a hazardous waste, DBDCD is now primarily involved in regulatory frameworks and waste management practices. Strict regulations and restrictions guide its use and disposal to mitigate the risks associated with its persistence and toxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 558-57-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 558-57:
(5*5)+(4*5)+(3*8)+(2*5)+(1*7)=86
86 % 10 = 6
So 558-57-6 is a valid CAS Registry Number.

Method for preparing bromodifluoroacetic compounds
-
, (2008/06/13)
The invention relates to a method for preparing bromodifluoroacetic compounds which comprises converting a 1,1-diflouro-1,2-dibromodihaloethane with oleum having 50-70% SO3 to a bromodifluoroacetyl halide (bromide or chloride) and then in reacting the latter directly with either an alcohol, or with water.
