Used in organic synthesis as a boronic ester reagent, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its stabilized boronate structure enhances handling and shelf life compared to free boronic acids. Commonly employed in pharmaceutical and agrochemical research for constructing complex aromatic frameworks. The phenoxy group can act as a directing or protecting moiety, improving selectivity in coupling processes. Suitable for solid-phase synthesis and combinatorial chemistry due to its stability under various reaction conditions.
