Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct biaryl and heteroaryl frameworks common in pharmaceuticals and functional materials. Its quinoxaline core acts as an electron-deficient aromatic system, making it valuable in the development of organic semiconductors, sensors, and luminescent materials. Also employed as a building block in medicinal chemistry for designing kinase inhibitors and other bioactive compounds due to the quinoxaline moiety’s biological activity. The boronate ester group allows for efficient and selective carbon-carbon bond formation under mild conditions, enhancing its utility in drug discovery and materials science.
