Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds, particularly in pharmaceutical and agrochemical research. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of drug candidates targeting kinases and other biological pathways. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems due to the presence of the methylpiperazine moiety, which can enhance solubility and bioavailability in final active compounds.
