Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronic ester structure offers improved stability and handling compared to the free boronic acid, making it suitable for solid-phase synthesis and high-throughput screening. Commonly employed in the preparation of biaryl compounds, especially in drug discovery for building complex aromatic frameworks. The neopentyl glycol ester group enhances crystallinity and purification, beneficial in multistep synthetic routes.
