Used as a specialized reagent in organotellurium chemistry, particularly in the synthesis of tellurium-containing organic compounds for research in medicinal chemistry and materials science. Its unique structure allows for selective functionalization in complex molecule assembly, making it valuable in developing novel antioxidants and studying redox-active biomolecules. Also employed in the preparation of chiral tellurium catalysts for asymmetric synthesis. Due to the sensitivity of tellurium functionalities, it is handled under inert atmosphere to prevent oxidation.
