Application

(4-Bromo-2,3,5,6-tetrafluorophenyl)hydrazine is primarily used as a building block in the synthesis of fluorinated pharmaceuticals and agrochemicals. Its reactivity allows for the construction of nitrogen-containing heterocycles, such as pyrazoles and indazoles, with enhanced metabolic stability. Researchers also employ it in materials science to develop fluorinated polymers with unique thermal and chemical resistance. The bromo substituent further enables cross-coupling reactions for structural diversification.
