Used as a silylating agent in organic synthesis, particularly for the protection of sensitive functional groups such as alcohols, amines, and acids. Its bulky structure provides high selectivity and stability, making it effective in complex molecule synthesis where steric control is important. Commonly employed in pharmaceutical and agrochemical research to modify reactivity and improve yield in multi-step reactions. Also serves as a precursor in the preparation of other organosilicon compounds used in materials science and catalysis.
