Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key boronic ester reagent in the synthesis of pharmaceutical intermediates and functionalized pyridine derivatives. Its boron-containing group enables efficient carbon-carbon bond formation under mild palladium catalysis, making it valuable in drug discovery and development. The methylsulfonyl group enhances reactivity and directs further functionalization, allowing selective construction of complex molecules. It is particularly useful in preparing bioactive compounds, including kinase inhibitors and other therapeutic agents. Its stability and reactivity profile make it suitable for automated synthesis and high-throughput screening in medicinal chemistry.
