2-Bromo-4-(trifluoromethyl)pyridine is a vital fluorinated pyridine organic synthesis building block.
The bromine substituent is highly active for Suzuki, Heck, Sonogashira and Buchwald-Hartwig cross-coupling reactions.
Trifluoromethyl group enhances lipophilicity, chemical stability and metabolic stability of target drug molecules.
It is widely used as key intermediate for kinase inhibitors, anti-tumor drugs, anti-inflammatory agents and CNS therapeutic compounds.
Also applied in medicinal chemistry compound library construction and SAR structure-activity relationship research, as well as agrochemical fine chemical synthesis.
