Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and targeted cancer therapies. Its boronic acid functionality enables Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing biaryl structures found in bioactive molecules. The protected hydrazine group allows for selective deprotection and further derivatization, facilitating the creation of hydrazide or acyl hydrazine moieties important in drug design. Commonly employed in medicinal chemistry for lead optimization and library synthesis in drug discovery programs.
