Used in organic synthesis as a key intermediate for cross-coupling reactions, particularly in the preparation of biologically active indole derivatives. Its boronate ester group enables Suzuki-Miyaura coupling, allowing the formation of C–C bonds with aryl or heteroaryl halides. This makes it valuable in pharmaceutical research for constructing complex molecules, especially in the development of drug candidates targeting neurological disorders, inflammation, and cancer. Commonly employed in medicinal chemistry for late-stage functionalization due to its stability and reactivity profile.
