664-03-9 Usage
Description
1-Bromo-2,3,4-trichloro-1,1,2-trifluorobutane, also known as Halon 1301, is a halogenated hydrocarbon compound that was widely used as a fire-extinguishing agent due to its high effectiveness in interrupting the chemical reaction that sustains combustion. However, it is known for its ozone-depleting properties and potential health hazards, leading to its discontinuation in the 1990s.
Used in Fire Protection Industry:
1-Bromo-2,3,4-trichloro-1,1,2-trifluorobutane was used as a fire-extinguishing agent for its exceptional ability to suppress fires by interrupting the chemical reaction that sustains combustion. It was particularly effective in enclosed spaces and for specific types of fires, such as those involving electrical equipment or flammable liquids.
However, due to its ozone-depleting properties and potential health hazards, including respiratory issues, skin irritation, and central nervous system effects, the production and use of 1-Bromo-2,3,4-trichloro-1,1,2-trifluorobutane have been largely discontinued since the 1990s. Its use is now regulated under international agreements such as the Montreal Protocol to protect the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 664-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 664-03:
(5*6)+(4*6)+(3*4)+(2*0)+(1*3)=69
69 % 10 = 9
So 664-03-9 is a valid CAS Registry Number.
