Used primarily in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. Its nitrile group allows for further functionalization, making it valuable in the construction of complex organic molecules, especially in pharmaceutical and agrochemical industries. The presence of the cyano group adjacent to the boronate ester enables selective transformations, supporting the synthesis of biaryl compounds and substituted nitriles that serve as intermediates in drug development. It is also employed in materials science for designing conjugated systems and functional polymers.
