Used as a sulfur-containing boronic acid intermediate in organic synthesis. It is mainly applied in Suzuki-Miyaura cross-coupling reactions for the preparation of conjugated aromatic compounds, organic semiconductor materials, OLED functional materials, and pharmaceutical research intermediates. The boronic acid functional group provides a versatile coupling handle for carbon-carbon bond formation.
