Used primarily as an intermediate in organic synthesis, this compound plays a key role in the preparation of sterically hindered amines and nitroxide radicals. It is especially valuable in the development of stable radical species used in polymer chemistry, such as in controlled radical polymerization techniques like NMP (Nitroxide-Mediated Polymerization). Its structure allows for effective regulation of polymer chain growth, leading to polymers with narrow molecular weight distributions. Additionally, derivatives of this compound find use in the design of antioxidants and light stabilizers for plastics, protecting materials from degradation due to UV exposure and oxidative stress. It is also explored in the synthesis of functional materials and as a building block in pharmaceutical research where a rigid, bulky amine scaffold is required.
