Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Particularly valuable in pharmaceutical and agrochemical industries for constructing naphthalene-based structures with high efficiency and selectivity. Its boronate ester group facilitates mild and catalytic coupling conditions, making it ideal for late-stage functionalization in drug development. Also applied in materials science for designing organic semiconductors and fluorescent dyes due to the extended aromatic system.
