Used as a specialized selenium-based reagent in organic synthesis, particularly in oxidation reactions where selective transformation of functional groups is required. It demonstrates utility in the preparation of selenoxide intermediates, which can undergo elimination to form alkenes from alkyl selenides. Its structure allows for controlled reactivity in mild conditions, making it suitable for use in complex molecule synthesis, including pharmaceuticals and natural products. Additionally, it serves as a precursor in the development of selenium-containing catalysts and functional materials with potential applications in materials science and medicinal chemistry.
