Used in organic synthesis as a key intermediate for pharmaceuticals, particularly in the preparation of kinase inhibitors and anti-cancer agents. Its boronic acid functionality enables Suzuki-Miyaura cross-coupling reactions, allowing the formation of carbon-carbon bonds in complex molecule assembly. Commonly employed in medicinal chemistry for constructing indole-based scaffolds, which are prevalent in bioactive molecules. Also utilized in the development of protease inhibitors and targeted therapies due to its structural compatibility with biological systems.
