Usage

General Description

5,5-DIMETHYL-4-PHENYL-1-PYRROLINE N-OXIDE, also known as DMPO, is a stable nitroxide radical commonly used as a spin trapping agent in biological and chemical systems. It is a synthetic free radical scavenger that reacts with and stabilizes short-lived free radicals, allowing for their detection and analysis. DMPO is used in various scientific applications, including in electron spin resonance (ESR) spectroscopy to study the behavior of free radicals in biological and chemical systems. It is also utilized in the development of novel antioxidants, anti-inflammatory agents, and radioprotective drugs. Due to its unique properties, DMPO plays a crucial role in advancing the understanding of free radicals and oxidative stress in various fields of research.
