Used as a highly effective radical scavenger and antioxidant in polymer systems, protecting materials from degradation caused by UV exposure and oxidative stress. Commonly employed in coatings, plastics, rubber, and cosmetic formulations to enhance durability, extend service life, and stabilize active ingredients against oxidation. Additionally, serves as a catalyst in oxidation reactions for organic synthesis, particularly the efficient conversion of primary alcohols to aldehydes or ketones, often in combination with co-oxidants such as sodium hypochlorite or bleach. Its high stability enables recyclability, high-purity products, and minimal byproducts. In biochemical research, it functions as a spin label for electron paramagnetic resonance (EPR) spectroscopy, facilitating the study of molecular dynamics, protein structures, and cell membrane properties. The stable radical nature allows precise monitoring of redox processes in both industrial and laboratory settings.
