Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds, which are key structures in pharmaceuticals and agrochemicals. Its boronic acid group enables stable yet reactive bonding with halogenated aromatics under palladium catalysis. Commonly employed in the development of liquid crystals, organic semiconductors, and functional materials due to the long nonyloxy chain enhancing solubility and phase stability. Also applied in sensor design where the phenylboronate moiety selectively binds diols for glucose or saccharide detection.
