Used in organic synthesis as a key building block for the preparation of biologically active compounds, particularly in the development of nucleoside analogs and antiviral agents. Serves as an intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical research. Its boronic acid functionality allows for selective transformations and conjugation with heterocyclic systems, making it valuable in medicinal chemistry for designing drug candidates targeting various diseases, including cancer and viral infections.
