Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates efficient coupling with aryl halides under mild conditions, making it valuable in the development of complex organic molecules, particularly in drug discovery and materials science. The ethylsulfinyl group can act as a directing or modulating functionality, influencing reactivity or serving as a precursor for further transformations.
