Used in organic synthesis as a protected boronic acid derivative for Suzuki-Miyaura cross-coupling reactions. The TBS (tert-butyldimethylsilyl) group protects the hydroxyl function, allowing selective reactivity at the boronic acid site during coupling. After the coupling reaction, the TBS group can be removed under mild conditions to reveal the free alcohol, enabling further functionalization. This compound is particularly useful in the synthesis of complex molecules such as pharmaceuticals and natural products where orthogonal protection strategies are required. Its stability and selective deprotection make it valuable in multi-step synthetic routes.
