1H-Benzimidazole, 4,5,6,7-tetrafluoro-(9CI) is a chemical compound belonging to the benzimidazole family, characterized by the presence of four fluorine atoms at positions 4, 5, 6, and 7. This heterocyclic aromatic organic compound is derived from benzene, with a nitrogen atom replacing one of the carbon atoms in the ring structure. The compound is represented by the formula C6H2F4N, with a molecular weight of 175.08 g/mol. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique properties, such as its ability to form hydrogen bonds and its potential to act as a chelating agent. The tetrafluorinated benzimidazole structure contributes to its stability and reactivity, making it a valuable building block in the development of new compounds with specific biological activities.

4920-46-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4920-46-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4920-46:
(6*4)+(5*9)+(4*2)+(3*0)+(2*4)+(1*6)=91
91 % 10 = 1
So 4920-46-1 is a valid CAS Registry Number.

Polyhalogenonitrobenzenes and derived compounds: Part 5. Improved preparations of 1,2,3,4-tetrafluoro-5,6-dinitrobenzene and 3,4,5,6-tetrafluoro-1,2-phenylenediamine, and the use of the latter for the synthesis of tetrafluorobenzheterocycles

Heaton, Alan,Hill, Mark,Drakesmith, Frederick

, p. 133 - 138 (2007/10/03)

The preparation of 2,3,4,5-tetrafluoro-6-nitroaniline (3) by amination of pentafluoronitrobenzene has been speeded up, scaled up and the yield increased by controlling the reaction by TLC monitoring and using 'dry column' chromatography. Compound (3) was readily converted to 1,2,3,4-tetrafluoro-5,6-dinitrobenzene (2) by peroxytrifluoroacetic acid and to 3,4,5,6-tetrafluoro-1,2-phenylenediamine (1) by SnCl2/HCl, Compound (1) was shown to be a versatile intermediate for the synthesis of tetrafluoro-benzimidazoles, -triazoles and -quinoxalines. The fungicidal activity of the latter are reported here.
