2,2,3,3-Tetrachloro-1,1,1-trifluoropropane, also known as CCl3CF2CCl3 or Halon 1211, is a colorless, volatile, and nonflammable liquid with a chloroform-like odor. It is a member of the halocarbon family and was widely used as a fire extinguishing agent due to its effectiveness in suppressing fires without leaving any residue. However, its production and use have been phased out in many countries, including the United States, under the Montreal Protocol, as it was found to be an ozone-depleting substance. The chemical has a molecular formula of C3Cl4F3 and a molecular weight of 203.83 g/mol. It is highly stable and does not decompose easily, which contributes to its persistence in the environment and potential for long-range transport. Despite its ban, it is still used in some specific applications, such as in the military and aerospace industries, where its fire-suppressing properties are deemed essential.

422-35-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 422-35-5 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 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 422-35:
(5*4)+(4*2)+(3*2)+(2*3)+(1*5)=45
45 % 10 = 5
So 422-35-5 is a valid CAS Registry Number.

19F nuclear magnetic resonance studies of halogenated propanes

Tanuma, T.,Ohnishi, K.,Okamoto, H.,Miyajima, T.,Morikawa, S.

, p. 259 - 284 (2007/10/02)

The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers.The pairs of atom gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts.The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of molecule.
