Used as an intermediate in pharmaceutical synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct complex indole derivatives. Its boronate ester and bromo functionalities allow sequential coupling steps, enabling the development of bioactive molecules and drug candidates. Commonly applied in research for creating analogs in medicinal chemistry, especially in oncology and CNS drug discovery. Also utilized in the preparation of fluorescent probes and functional materials due to the indole core’s photophysical properties.
