Widely used in cross-coupling reactions, particularly in Suzuki-Miyaura coupling, this compound serves as a key intermediate in the synthesis of pharmaceuticals and biologically active molecules. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development. It is especially useful in constructing complex heterocyclic systems found in kinase inhibitors and other therapeutic agents. The protecting group (Boc) enhances stability and solubility during synthetic transformations, allowing selective deprotection and further functionalization in multi-step syntheses.
