Triphenylsilanol is widely used as a key intermediate in the synthesis of organosilicon compounds. It plays a significant role in the production of silicone resins, which are utilized in coatings, adhesives, and sealants due to their thermal stability and water resistance. Additionally, it is employed in the preparation of silane coupling agents, which enhance the bonding between organic and inorganic materials in composites and surface treatments. In the pharmaceutical industry, it serves as a building block for creating siloxane-based polymers used in drug delivery systems. Its applications also extend to the electronics sector, where it contributes to the fabrication of insulating materials and protective coatings for electronic components.
