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 aryl-heteroaryl frameworks found in pharmaceuticals and agrochemicals. The indole moiety 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 palladium catalysis, making it suitable for late-stage functionalization in complex molecule assembly. Commonly employed in medicinal chemistry and materials science for building nitrogen-containing aromatic systems with tailored electronic properties.
