Used as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its stability and reactivity make it valuable for constructing biaryl compounds, which are common structural motifs in pharmaceuticals, agrochemicals, and functional materials. The trifluoroborate group enhances handling and shelf life compared to boronic acids, while the bromine substituents allow for selective coupling. It is particularly useful in the development of complex aromatic systems where controlled reactivity is required.
