Used primarily as an intermediate in pharmaceutical synthesis, especially in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in the development of active pharmaceutical ingredients (APIs). Commonly applied in the preparation of indole-based drug candidates, including those targeting inflammation, cancer, and neurological disorders. The tert-butyl ester group offers stability during reactions and can be easily deprotected when needed. Preferred in research settings for its reliability in generating complex molecular structures with high yields.
