Used primarily as an intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group readily participates in palladium-catalyzed couplings with aryl or vinyl halides, making it valuable in pharmaceutical and agrochemical research for constructing substituted aromatic and cyclopropane-containing structures. The ethyl ester functionality allows further transformations, such as hydrolysis to the corresponding carboxylic acid or use in peptide-like coupling reactions. Its stability and reactivity profile make it suitable for late-stage functionalization in drug discovery and materials science.
