Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, it facilitates the synthesis of complex organic compounds, particularly in pharmaceutical research. Its boronic ester group enables efficient carbon-carbon bond formation, making it valuable for creating drug candidates and bioactive molecules. Additionally, it is employed in the development of materials science applications, such as organic electronics and polymers, due to its ability to introduce cyclopropyl and pyrimidine moieties into target structures. Its stability and reactivity under mild conditions make it a versatile reagent in organic synthesis.
