Used primarily in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. It enables the formation of carbon-carbon bonds, particularly in the construction of biaryl or heteroaryl frameworks found in pharmaceuticals and agrochemicals. The indole core makes it valuable for synthesizing bioactive molecules, including drug candidates targeting neurological disorders, inflammation, and cancer. Its boronate ester group offers stability and reactivity under mild conditions, making it suitable for late-stage functionalization in complex molecule assembly. Commonly employed in medicinal chemistry and materials science for building advanced intermediates.
