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, making it valuable in the construction of complex organic molecules, especially in pharmaceutical and agrochemical research. The ethyl ester group can be easily hydrolyzed or transformed into other functional groups, allowing further derivatization. Its stability and reactivity profile make it suitable for late-stage functionalization in drug discovery and materials science.
