CYPMPO is widely used as a spin trap in electron paramagnetic resonance (EPR) spectroscopy to detect and study short-lived free radicals. Its application is particularly significant in biochemical and medical research, where it helps in understanding oxidative stress mechanisms by capturing reactive oxygen species (ROS) such as superoxide and hydroxyl radicals. This compound is also utilized in material science to investigate radical intermediates in polymerization processes. Additionally, CYPMPO's stability and sensitivity make it a valuable tool in environmental studies for analyzing radical formation in various chemical reactions.
