Used primarily in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to create complex biaryl structures. Its boronic acid group facilitates the formation of carbon-carbon bonds, making it valuable in pharmaceutical and materials research. Commonly employed in the development of drug intermediates and active pharmaceutical ingredients (APIs). Also utilized in the preparation of advanced materials, such as organic semiconductors and polymers, due to its ability to introduce cyclopropyl and cyano functional groups into molecular frameworks. Its stability and reactivity make it a versatile reagent in medicinal chemistry and material science applications.
