Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active chromene derivatives. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of fluorescent probes and optoelectronic materials due to the chromene backbone’s photophysical properties. Also applied in medicinal chemistry for constructing libraries of heterocyclic compounds with potential anticancer, antimicrobial, or anti-inflammatory activity.
