420-47-3 Usage
Uses
Used in Firefighting Applications:
1-bromo-1,1-difluoro-ethane is used as a fire-extinguishing agent for its ability to extinguish a wide range of fires, including those involving flammable liquids and electrical equipment. Its non-flammable nature and effectiveness make it suitable for use in portable fire extinguishers and some firefighting equipment.
However, due to its classification as a potent ozone-depleting substance, its use in firefighting has been largely phased out in many countries. The environmental impact of 1-bromo-1,1-difluoro-ethane has led to heavy restrictions and regulations under the Montreal Protocol and other international agreements.
Used in Organic Synthesis:
Despite its phased-out use in firefighting, 1-bromo-1,1-difluoro-ethane is sometimes used as a solvent in organic synthesis. Its properties make it a valuable component in certain chemical processes, although its use in this context is also subject to environmental considerations and regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 420-47-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 420-47:
(5*4)+(4*2)+(3*0)+(2*4)+(1*7)=43
43 % 10 = 3
So 420-47-3 is a valid CAS Registry Number.

A Convenient Access to 1,1-Difluoroethyl Triflate and Iodide
Marival-Hodebar, Laurence,Tordeux, Marc,Wakselman, Claude
, p. 192 - 193 (2007/10/03)
1,1-Difluoroethyl trifiate obtained from 1,1-difluoroethylene and trifluoromethanesulfonic acid is converted into its corresponding iodide by the action of iodide anion in diethyl ketone.
