Used as a specialty reducing agent in organic synthesis, particularly in the preparation of silicon-containing polymers and organosilicon intermediates. Its unique Si–Si and Si–H bonds allow for selective hydrosilylation reactions, making it valuable in the development of silicone-based materials, coatings, and adhesives. Also employed in research settings for the surface modification of semiconductors due to its ability to introduce silicon-hydrogen functionalities onto substrates. Due to its high reactivity and sensitivity to moisture, it is handled under inert atmosphere conditions in controlled environments.
