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 and heteroaryl frameworks found in pharmaceuticals, agrochemicals, and functional materials. The presence of the benzo[d]oxazole ring adds electron-rich character and stability, making it valuable in the development of fluorescent dyes, optoelectronic materials, and bioactive molecules. Its boronate ester group is stable under various conditions and allows for selective transformations, facilitating late-stage functionalization in drug discovery and materials science.
