Chlorotriphenylsilane is widely used as a key reagent in organic synthesis, particularly in the preparation of silicon-containing compounds. It serves as a protective group for alcohols and phenols, enabling selective reactions in complex molecular frameworks. This compound is also employed in the production of silyl ethers, which are intermediates in the synthesis of pharmaceuticals and fine chemicals. Additionally, it plays a role in the modification of surfaces and materials, enhancing properties like hydrophobicity or adhesion. In polymer chemistry, it is utilized to introduce phenylsilane groups into polymers, improving their thermal stability and mechanical characteristics. Its versatility makes it valuable in both industrial and research applications.
