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 boronic acid functionality allows for selective transformations in complex molecule assembly, particularly in drug discovery where aryl boronic derivatives are key intermediates. The sulfonyl group enhances solubility and can influence electronic properties, making it useful in tuning reactivity during coupling processes. Also applied in the preparation of biaryl compounds and functionalized aromatic systems found in bioactive molecules.
