Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key boronic ester reagent for forming carbon-carbon bonds in organic synthesis. Its stability and reactivity make it valuable for constructing biaryl and aryl systems found in pharmaceuticals, agrochemicals, and advanced materials. The tert-butyl ester group remains intact under typical coupling conditions, allowing further functionalization in multi-step syntheses. It is particularly useful in drug discovery and development for building complex aromatic frameworks with high selectivity and yield.
