Application

2,4,5-Trifluorobenzyl Bromide serves as a versatile building block in the synthesis of fluorinated active pharmaceutical ingredients (APIs), including kinase inhibitors and antiviral agents. Its electron-withdrawing trifluoromethyl groups facilitate Suzuki-Miyaura and Buchwald-Hartwig cross-coupling reactions. The compound is also employed in agrochemical research to develop herbicides with enhanced metabolic stability. Researchers value its reactivity in benzylic functionalization for constructing complex fluorinated scaffolds.
