Used as a silylating agent in organic synthesis, particularly for the protection of hydroxyl and amino groups in sensitive molecules. Its dual silyloxy functionality allows for controlled reactivity and enhanced stability of intermediates in nucleoside and carbohydrate chemistry. Commonly employed in the preparation of silylated pyrimidine derivatives for pharmaceuticals and agrochemicals. Also serves as a reagent in the synthesis of silicon-containing polymers and in materials science for surface modification of silica-based substrates.
