Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 453-20-3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 453-20-3
Synthesis and fungicidal activities of perfluoropropan-2-yl-based novel quinoline derivatives
A series of novel perfluoropropan-2-yl-based quinoline derivatives was designed and synthesized utilizing tebufloquin as the lead compound. The structures of all the newly synthesized compounds were confirmed by spectroscopic data 1HNMR, MS and elemental analysis. The results of bioassay indicated that these compounds exhibited potent fungicidal activities against Erysiphe graminis. Especially, compound 8c displayed excellent activity with EC50 value at 1.48 mg / L, which was better than that of the commercialized fungicide-tebufloquin. The structure-activity relationship for these new compounds was also discussed.
