53780-44-2 Usage
General Description
3-Chloro-4,5-difluoronitrobenzene is a chemical compound with the molecular formula C6H3ClF2NO2. It is a nitrobenzene derivative that features a chlorine atom in the ortho position and two fluorine atoms in the para positions of the benzene ring. 3-Chloro-4,5-difluoronitrobenzene is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used in the production of dyes and pigments. 3-Chloro-4,5-difluoronitrobenzene is a hazardous chemical and should be handled with care due to its toxic and potentially harmful properties.
Check Digit Verification of cas no
The CAS Registry Mumber 53780-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,8 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53780-44:
(7*5)+(6*3)+(5*7)+(4*8)+(3*0)+(2*4)+(1*4)=132
132 % 10 = 2
So 53780-44-2 is a valid CAS Registry Number.

Synthesis of fluorinated halonitrobenzenes and halonitrophenols using tetrafluoroethylene and buta-1,3-dienes as starting building blocks
Lipkind, M. B.,Nefedov, O. M.,Volchkov, N. V.
, p. 2156 - 2163 (2022/01/22)
The gas-phase copyrolysis of tetrafluoroethylene with buta-1,3-diene in a flow reactor at 495–505 °C produces 3,3,4,4-tetrafluorocyclohex-1-ene, which selectively converted to 1,2-difluorobenzene or 1-chloro-2,3-difluorobenzene. The latter can be converted to 2-chloro-3,4-difluoronitrobenzene, 2,3,4-trifluoronitrobenzene, 2,3-difluoro-6-nitrophenol, or 2-chloro-3-fluoro-4-nitrophenol via nitration, fluorodechlorination, and hydrolysis reactions.
