Used as a reagent in organic synthesis, particularly in fluorination reactions due to the presence of trifluoroborate group. It serves as a stable source of nucleophilic fluoride and participates in transition-metal-catalyzed cross-coupling reactions, enabling the formation of carbon–fluorine bonds in pharmaceuticals and agrochemicals. Its benzyloxyphenyl moiety enhances solubility and stability in common organic solvents, making it suitable for use in mild reaction conditions. Also applied in the synthesis of labeled compounds for positron emission tomography (PET) due to favorable isotopic labeling potential.
