Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its arylboronic acid functionality allows for the preparation of biaryl compounds, which are common structural motifs in drug discovery. Also employed in the synthesis of ligands and functional materials where precise molecular architecture is required. The presence of ethyl groups enhances steric and electronic tuning in target molecules.
