Used as a reagent in organic synthesis for the protection of hydroxyl groups in alcohols. It is particularly effective in the formation of silyl ethers, which are stable under various reaction conditions, allowing for selective transformations in complex molecules. This chemical is also employed in the preparation of silicone-based materials, where it acts as a precursor for introducing phenyl groups into the polymer structure. Additionally, it finds application in surface modification, where it is used to create hydrophobic coatings on glass and other substrates, enhancing their resistance to moisture and environmental factors.
