Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active compounds, particularly in pharmaceutical research. Its boronic acid functionality enables efficient carbon-carbon bond formation with aryl or heteroaryl halides, making it valuable in constructing complex thiophene-based structures. The presence of protected amine and ester groups allows for further selective transformations, facilitating the development of drug candidates in medicinal chemistry, especially in the design of kinase inhibitors and other therapeutic agents.
