Used as a spin trap in electron paramagnetic resonance (EPR) spectroscopy to detect and identify short-lived free radicals in biological systems. It reacts with reactive oxygen species such as superoxide and hydroxyl radicals, forming stable spin adducts that can be measured and analyzed. Commonly applied in studies of oxidative stress in cells, tissues, and biochemical assays, helping researchers understand radical involvement in disease mechanisms, drug metabolism, and antioxidant activity. Its diisopropyl groups enhance lipophilicity, improving cell membrane permeability and making it suitable for in vitro and ex vivo experiments.
