Widely used in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. It serves as a key intermediate for introducing the 4-tert-butylphenyl group into complex molecules, especially in the preparation of pharmaceuticals, agrochemicals, and functional materials. Its stability and reactivity make it suitable for palladium-catalyzed transformations under mild conditions. Commonly employed in research and industrial settings for constructing biaryl frameworks in drug discovery and materials science.
