Used primarily as an intermediate in the synthesis of liquid crystal materials for display technologies. Its reactive trichlorosilyl group enables covalent bonding to silica surfaces, making it valuable in surface modification for chromatography supports and sensor coatings. Also employed in the production of specialty silanes for adhesives and sealants, where it enhances adhesion between organic polymers and inorganic substrates. Its biphenyl structure contributes to thermal stability and rigidity, beneficial in high-performance composite materials.
