Used in organic synthesis and pharmaceutical research, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Its boronic acid group enables the construction of complex quinoxaline derivatives, which are valuable in developing bioactive molecules, including potential antiviral, antibacterial, and anticancer agents. Also applied in materials science for designing fluorescent probes and organic electronic materials due to the quinoxaline core’s favorable photophysical properties.
