Used as a protecting group in organic synthesis, particularly for alcohols, to prevent unwanted reactions during complex chemical processes. It is also employed in the production of silicon-based polymers and resins, where it acts as a cross-linking agent to enhance material properties. Additionally, it serves as a reagent in the modification of surfaces to impart hydrophobic characteristics, making it valuable in coatings and waterproofing applications. Its role in the synthesis of specialty chemicals and intermediates further highlights its versatility in industrial chemistry.
