General Description
2-Bromo-4-trifluoromethyl-3-quinolinecarboxylic acid is a chemical compound with the formula C11H5BrF3NO2. It is a quinoline derivative with a bromine atom and a trifluoromethyl group attached to the 2 and 4 positions, and a carboxylic acid group at the 3 position. 2-BroMo-4-trifluoroMethyl-3-quinolinecarboxylic acid is often used as a building block in the synthesis of pharmaceuticals and agrochemicals, due to its versatile reactivity and ability to introduce fluorine and bromine functionality into organic molecules. Its unique structure and reactivity make it an important intermediate in the production of various bioactive compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 590372-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,0,3,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 590372-20:
(8*5)+(7*9)+(6*0)+(5*3)+(4*7)+(3*2)+(2*2)+(1*0)=156
156 % 10 = 6
So 590372-20-6 is a valid CAS Registry Number.

4-(Trifluoromethyl)quinoline derivatives

Under carefully controlled conditions, ethyl 4,4,4-trifluoroacetoacetate (ethyl 4,4,4-trifluoro-3-oxobutanoate) can be condensed with anilines and subsequently cyclized to give 4-trifluoromethyl-2-quinolinones 1 although only in poor yield. Heating these products with phosphoryl tribromide affords 2-bromo-4-(trifluoromethyl)quinolines 2 which can be converted into 4-(trifluoromethyl)quinolines 3 by reduction, 4-trifluoromethyl-2-quinolinecarboxylic acids 4 by permutational halogen/metal exchange followed by carboxylation, and 2-bromo-4-trifluoromethyl-3-quinolinecarboxylic acids 5 by consecutive treatment with lithium diisopropylamide and dry ice. Debromination of acids 5 makes 4-trifluoromethyl-3-quinolinecarboxylic acids 6 available. As at any time 2-trifluoromethyl-4-quinolinones 9 may form instead of the expected isomers 1, the structures have to be assigned on the basis of unequivocal NMR spectral criteria.
