Used as a specialized reagent in organic synthesis, particularly in silicon chemistry and the modification of polymer surfaces. It acts as a mild antimony-based coupling agent in the formation of siloxane networks, useful in creating heat-resistant and chemically stable coatings. Employed in research settings for the preparation of organoantimony compounds with potential catalytic properties. Its high silyl content makes it effective in passivating reactive surfaces and stabilizing sensitive intermediates in moisture-sensitive reactions. Also explored in the development of specialty materials for electronics and protective films due to its hydrophobic and thermally stable characteristics.
