20411-84-1 Usage
General Description
2,2-Dichloro-3,3,3-trifluoropropan-1-ol, also known as HFPO-DA or GenX, is a synthetic chemical compound used in the production of fluoropolymers. It is considered a replacement for perfluorooctanoic acid (PFOA), a persistent and bioaccumulative chemical that has been phased out due to environmental and health concerns. However, HFPO-DA has come under scrutiny for its potential health and environmental impacts. Studies have shown that it can accumulate in the environment and in tissues of living organisms, and it has been linked to various adverse health effects, including developmental and reproductive toxicity. Due to its persistence and potential for bioaccumulation, efforts are being made to regulate and reduce the use of HFPO-DA in industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 20411-84-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,1 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20411-84:
(7*2)+(6*0)+(5*4)+(4*1)+(3*1)+(2*8)+(1*4)=61
61 % 10 = 1
So 20411-84-1 is a valid CAS Registry Number.

The title compound 1, which can be regarded as synthetic equivalent of substituted 1,1,1-trifluoroacetone 2, is prepared by Zn-induced reductive addition of 1,1,1-trichloro-2,2,2-trifluoroethane (3) to formaldehyde (4).A brief survey of the scope of this C-C-bond formation leading to a variety of new CF3-containing synthetic building blocks is also given.
