420-48-4

Dichlorofluoroiodomethane, also known as CHCI2FI or Halon 1211, is a halogenated alkane compound that was widely used as a fire extinguishing agent due to its ability to suppress fires without leaving a residue. It is a colorless, odorless, and non-conductive gas at room temperature. However, its production and use have been phased out in many countries due to its high ozone depletion potential and contribution to the depletion of the ozone layer. Despite its effectiveness as a fire suppressant, the environmental impact of dichlorodifluoromethane has led to the development and adoption of more eco-friendly alternatives for fire suppression.

420-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 420-48-4 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 8 respectively.
Calculate Digit Verification of CAS Registry Number 420-48:
(5*4)+(4*2)+(3*0)+(2*4)+(1*8)=44
44 % 10 = 4
So 420-48-4 is a valid CAS Registry Number.

PREPARATION OF HALO-F-METHANES VIA POTASSIUM FLUORIDE-HALOGEN CLEAVAGE OF HALO-F-METHYLPHOSPHONIUM SALTS

Burton, D. J.,Shin-Ya, S.,Kesling, H.S.

, p. 89 - 98 (2007/10/02)

Treatment of halo-F-methylphosphonium salts with potassium fluoride and halogen (I2, Br2, ICl, IBr) gives modest yields of halo-F-methanes.This method of preparation augments the classical Hunsdiecker approach to these materials.
